It will only break its ability to read large files (> 2GB). That is what
_FILE_OFFSET_BITS is for.

Do you really want -m64 at all ? It is only necessary if you want to
build 64-bits binaries when running on a 32-bits kernel. Do you really
want to build ppc64 binaries on ppc, and s390x binaries on s390 ?
Wouldn't it be better to build such binaries respectively on ppc64 and
s390x ?
