There were a few straggling expansion parameter removals left for
getVar/getVarFlag where the odd whitespace meant they were missed
on previous passes. There were also some plain broken ussages such
as:

d.getVar('ALTERNATIVE_TARGET', old_name, True)
path = d.getVar('PATH', d, True)
d.getVar('IMAGE_ROOTFS', 'True')

which I've corrected (they happend to work by luck).

getVar() now defaults to expanding by default, thus remove the True
option from getVar() calls with a regex search and replace.

Search made with the following regex: getVar ?\(( ?[^,()]*), True\)

There are architectures which support running in 32 and 64 bit
flavours however the simulation is provided in a specific QEMU
setting, requiring us to use a different binary. This patch allow this
to be done using, for example:

QEMU_TARGET_BINARY_ppce5500 = "qemu-ppc64abi32"

The e5500 and e6500 cpu types are not supported by native qemu, set the value
of -cpu to e500mc. Without this change, build will fail for packages which use
qemuwrapper in compile phase due to the following error.
| Unable to find CPU definition

e.g. gobject-introspection

The class had qemu_run_binary() which was not suitable for gobject-introspection,
as it required the name of the binary to run.

qemu_wrapper_cmdline() returns just the command line string needed to run
binaries, and does not require the binary name.

QEMU_EXTRAOPTIONS is a way to add PACKAGE_ARCH specific options to the
qemu_run_binary qemu commandline. The base QEMU_EXTRAOPTIONS variable
(ie without a PACKAGE_ARCH suffix) is not used, so defining it, either
directly or via an over-ride has no effect.

Although previously an over-ride for _armv7a was used, it did nothing
for most armv7a builds, which typically use PACKAGE_ARCH values such
as "cortexa9hf-neon". In practice this worked OK since without a -cpu
option, qemu-arm will default to emulating a CPU which supports all
required architecture levels.

qemu-arm (v2.5.0) with no -cpu option has been confirmed to
successfully run binaries built for armv7ve.

The variable name for QEMU_EXTRAOPTIONS is constructed programmatically, so we
need an explicit variable dependency, otherwise changes to it won't cause e.g.
qemuwrapper-cross to be rebuilt.

These need to be based on PACKAGE_ARCH rather than TARGET_ARCH, as we aren't
using overrides for this.

The 'overrides' here are PACKAGE_ARCH based and hence not overrides
as such and the _append wasn't working in many cases. This adjusts the
code to use PACKAGE_ARCH as the accessor and ensures the variables
work as expected. This fixes various segfaults and ensures postinsts
run at build time rather than on the target system.

The bug was introduced in http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=7efad8a1b56df6ee07c12ad360c0493d7b1d6d23.

* in some cases (e.g. with external toolchain which doesn't respect our
  reasonably old version set in OLDEST_KERNEL) it's possible to have libc
  which requires newer kernel than what we have on builders, qemu supports
  -r param to use different uname than what's returned by host system.
* change qemu_run_binary to pass -r ${OLDEST_KERNEL} and add the same to
  QEMU_OPTIONS which are used by qemuwrapper-cross
* maybe we should eventually convert all qemu_run_binary usages always include
  qemuwrapper-cross dependency and always call qemu through that (it
  seems very strange that qemu_target_binary is called from qemuwrapper
  and for allarch recipes it can return qemu-allarch as qemu binary).

  qemu_run_binary is used by:
  meta/classes/gtk-immodules-cache.bbclass:            ${@qemu_run_binary(d, '$D', '${bindir}/gtk-query-immodules-$maj_ver.0')} \
  meta/classes/qemu.bbclass:def qemu_run_binary(data, rootfs_path, binary):
  meta/recipes-core/systemd/systemd_213.bb:         ${@qemu_run_binary(d, '$D', '${base_bindir}/udevadm')} hwdb --update \
  meta/recipes-graphics/pango/pango.inc:    ${@qemu_run_binary(d, '$D','${bindir}/${MLPREFIX}pango-querymodules')} \

  and qemuwrapper directly by:
  scripts/postinst-intercepts/update_font_cache:PSEUDO_UNLOAD=1 qemuwrapper -L $D -E LD_LIBRARY_PATH=$D/${libdir}:$D/${base_libdir}\
  scripts/postinst-intercepts/update_pixbuf_cache:PSEUDO_UNLOAD=1 qemuwrapper -L $D -E LD_LIBRARY_PATH=$D/${libdir}:$D/${base_libdir}\
