Correctly setup LDADD with regards to libstand. The submitter points
out that "on amd64, libstand.a is compiled for i386, but is still installed
under ${WORLDTMP}/usr/lib instead of ${WORLDTMP}/usr/lib32.  Even if it
would be installed there, ld on amd64 is set up incorrectly with a
${TOOLS_PREFIX}/usr/lib/i386 default path, so it wouldn't link.  The reason
it does link under gcc is that gcc passes -L${WORLDTMP}/usr/lib twice,
even for -m32 builds, which is also incorrect, but accidentally works in
this case."
