* ltmain.in: When using gcc, pass -mfoo to the linker

via $compiler_flags in order to pass architecture information to
the linker (e.g. 32 vs 64-bit). This may also be accomplished via
-Wl,-mfoo but this is not reliable with gcc because gcc may use
-mfoo to select a different linker, different libraries, etc, while
-Wl,-mfoo simply passes -mfoo to the linker. If there is a better
solution, please let me know what it is.
