Clang needs to be told which target it is building for when cross
compiling.

Hi Joel,

Thanks!

Tested-by: Daniel Axtens <dja@axtens.net> # powerpc 64-bit BE

This solves one of the 2 issues I have in building for 64-bit BE with
clang. The other is the VDSO32 stuff, and I hope to send a patch for
that soon.

Regards,
Daniel
