This code was abstracted out of Cody P Schafer's multilib patch. It doesn't seem right having architecture dependent code in a specific libc implementation script. So this patch breaks it out into scripts/build/arch/<arch>.sh in a function: multilib_target_to_build="$(CT_DoArchMultilibTarget 'multi_flags' 'target-in')" Note that this function gets called on each multilib variant with different sets of compiler flags supplied in 'multi_flags'. The caller will first filter the flags so that there is no conflicting flags (e.g., no '-m32 -m64') supplied. Changed by Alexey Neyman: - make option analysis check specific option rather than match global options string as a whole. Moreover, old code did not handle multiple options in the same multilib, e.g. '-m64 -mlittle'. - fixed substitutions in powerpc.sh (*le variants did not match the pattern in the shell parameter expansion) - make s390.sh actually apply the flags it gathered from the options. - straighten the spaghetti in x86.sh by setting two flags, arch & abi. Also, do not depend on "gnu" being the last part - we can have '*-uclibcx32', for example.
