This series fixes two bugs with configure's cross compilation detection: - first, --cross-cflags is not obeyed by pc-bios/ compilation
- second, on a ppc64le machine, the host compiler can be used for ppc64 tests/tcg; however, this is not being done because $cpu does not match the target. Likewise, on an x86_64 machine the host compiler can be used to build both i386 tests/tcg and pc-bios/optionrom, but the special casing done by the configure script only covers the latter. The two are related because, if only the first was fixed, pc-bios/optionrom would use either the i386 or the x86_64 cflags depending on which cross compiler was found. So patches 2-4 tackle not just the cross CFLAGS problem with pc-bios, but also the biarch compiler problem with i386 and ppc. Patch 5 then covers the other biarch compilers. The other two patches are just cleanups.
