Do you have a seperate /lib directory for 32bit libraries?  For Linux on
ppc64,
we compile 32bit by default.  If we want to compile in 64bit mode, besides
adding
a "-m64" to both the CROSS_CFLAGS and LDFLAGS, we must also point LIB_DIR
to
/lib_64...where are 64bit libraries are stored.  The gcc compiler is the
same for
us for both 32bit and 64bit compiles for the newer distro releases...but we
must
set the CC and AR for older distro releases, where a 64bit gcc
cross-compiler is
required.
