[OpenBIOS] [PATCH] switch-arch: select 64bit compiler if 32bit compiler is not found

On Fedora, powerpc64 cross-compiler is part of the distro, not
the powerpc32 compiler.
As I'm lazy and powerpc64 cross-compiler is able to generate
32bit binaries, this patch modifies switch-arch to allow
to use cross-compiler from a list of architectures instead of
only the target architecture.
I've modified only the powerpc32 target, as I'm not able to test
the other architectures (and Fedora provides only cross-compiler
for powerpc).
