[ewg] building userspace on ppc64 is broken

[Yosef Etigin]

While building user-space binaries on ppc64, the libs are placed
in /usr/lib64, but they are built as 32 bit. This happens because
in ofed 1.2 CFLAGS=-m64 was passed by the environment from the
install script. What do you think about doing somthing like this
in the spec files to solve the problem?
