- add a task to setup multilib configuration for target gcc
- this commit adapts Nitin Kamble's work to gcc 4.7
- use a hash for storing arch-dependent multilib options
- patch gcc in order to use the multilib config files from the
build directory
Tests:
root@qemux86-64:~# gcc -m64 t.c -o t
root@qemux86-64:~# file t
t: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped
root@qemux86-64:~# ./t

Without this set, in the case host=target (which it does for on-target
gcc), the native header directory is set to the target sysroot with
no prefix. This means it would look for sdt.h on the build system
instead of in the target headers and this can lead to build failures
and is host contamination of the build.
The correct fix is to explicitly set the native header directory to
the correct location and then the headers get detected correctly.

Otherwise it assumes / as sysroot on build host and starts
searching for directories in there.

this option by default points to /usr/local no matter
what so we cant let it sit on sidelines otherwise it
will access host machine's /usr/local which may not
be desired. So disable this option. This also helps in making
gcc's shared state more consistent

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.
The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.
Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.
