When installing SDK in a non-default location and the path length
of the SDK install location is longer than the path length of the
default SDK location, relocation of .ldsochache section will overwrite
file location outside of the .ldsocache section size.
In addition, additional checks were added to ensure that any
path in sections .gccrelocprefix and .ldsochache will not exceed
the space allocated for it within the file, which would also result
in file corruption.

When fixing paths for .gccrelocprefix section, it will corrupt the next
entry during updating the current one if "new_prefix" length is more
than "DEFAULT_INSTALL_DIR", this problem is obvious on the code, but it's
only found when install sdk onto a net file system.

Being able to build a nativesdk gcc is useful, particularly in cases
where the host compiler may be of an incompatible version (or a 32
bit compiler is needed).
Sadly, building nativesdk-gcc is not straight forward. We install
nativesdk-gcc into a relocatable location and this means that its
library locations can change. "Normal" sysroot support doesn't help
in this case since the values of paths like "libdir" change, not just
base root directory of the system.
In order to handle this we do two things:
a) Add %r into spec file markup which can be used for injected paths
such as SYSTEMLIBS_DIR (see gcc_multilib_setup()).
b) Add other paths which need relocation into a .gccrelocprefix section
which the relocation code will notice and adjust automatically.
This patch adds tweaks to the relocation script to handle the
new section too.

When toolchain directory is changed to execute mode, some non-executable
files or empty files are sorted. This will lead to the below error:
Extracting SDK...done
Setting it up...Traceback (most recent call last):
File "..._SDK/relocate_sdk.py", line 208, in <module>
arch = get_arch()
File "..._SDK/relocate_sdk.py", line 39, in get_arch
ei_mag0,ei_mag1_3,ei_class = struct.unpack("<B3sB11x", e_ident)
struct.error: unpack requires a string argument of length 16
To call get_arch and parse_elf_header, we should ensure the sorted file
is bigger than 64 byte.

Python 2.4 does not support the 'b' string literal or the
keyword 'as' in exception handling. Python 3 does not accept
the old method of exception handling and defaults to unicode.
The b() function converts strings to bytes on Python 3 and
using sys.exc_info() avoids the exception handling syntax.

Strings in Python 3, by default, are assumed to contain unicode
characters. In previous versions of python (<3), unicode strings are
explicitly declared with u"abc". If not, than they're automatically
converted to bytes. This doesn't happen anymore in Python 3.
Since we're dealing with binary files, opened in byte mode, make sure
that we explicitly convert all strings to bytes to make both python 2
and 3 happy.
Other changes:
* add a safety check to make sure relocation did not change the file
size;
* a couple of cosmetic changes (wrap long lines so that we don't have
to scroll to reach the end of them);

Avoid the chicken / egg problem of an SDK that provides a working
python but requires that version of python to extract itself. The
RHEL 5.x systems and some other enterprise Linux systems ship with
python 2.4.x as the default python. We need to at least be able to
extract work executables even if we never use the the host provided
python again.

There are two cases of corruption that the relocate_sdk.py was not correctly
dealing with.
1) SDK Extras should be left alone
Extra external binaries included in an SDK that were linked against the
host's version of /usr/lib/ld-so.so should not get a relocation applied.
In the case that was discovered these were LSB compliant binaries that
already worked on many hosts.
2) If the interp section is too small generate an error
In the case of the qemu user code, it was using its own .ld file
to link the executables which overrides the default in the nativesdk
binutils. This generated host executables which had a interp section
that was too small to relocate.
Now the relocate_sdk.py will print an error and continue on such that
the error can be fixed by a developer without having to do the
difficult task of debugging why it is crashing or not loading correctly.

The problem: SDK binaries were not properly relocated when the SDK
was installed into a path that had a length less than the default one.
Apparently, there were two problems here: the padding was done wrong
(the size of one program header table entry was used instead of the
program section size) and the new padded string was not used at all.

If the files being relocated are already used by other processes the
relocate script will fail with a traceback. This patch will trap any IO
errors when opening such a file and gracefully report them to the user.
Also change the exit code from 1 to -1 for a better adt-installer user
experience (like pointing the user to the adt_installer.log).

This script will be embedded in the SDK tarball and will be called by
the SDK installer. It replaces the interpreter path in all binaries and
it also changes the ld.so.cache and SYSDIRS in dynamic loader.
