IIRC, this is a flag for the linker, so you have to use -Wl,-xarch=v9
so that GCC doesn't attempt to understand the flag itself, and passes
it literally to the linker.  I'd think -m64 might implicitly pass this
flag to the linker, but I can't see any hooks to do it in the GCC
configuration files.  Try to use just -m64 -v and see whether the flag
shows up in the linker command line.  If not, pass it in explicitly
as suggested above.

Wow!  Cool :-)
