  To: buildroot

Add a BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS which will be referenced by the
gobject-introspection package. This also has the added benefit of making the
config file conform to other package standards such as Valgrind.

Add depends on !BR2_powerpc_620 && !BR2_powerpc_630 && !BR2_powerpc_970 to
Config.in.host as these are not currently supported cpus by qemu.

Add a new variable in qemu.mk: HOST_QEMU_CPU_TUNE. When qemu-$(ARCH) is
called, some architectures require a -cpu flag to be passed, or else a
segfault may occure when building .gir files.
For PowerPC, many of these cpu's need a specific CPU flag to be passed
via the command line.
