Exclude ld.mcld from GCC package

ld.mcld is built along with llvm-3.2 because it use LLVM as STL.
It is then deployed/packaged to GCC directories via deploy-host-mcld.sh
If we call build-gcc.sh again ld.mcld can be packaged with GCC
by accident.  This is normally okay because package-release.sh
unpack ld.mcld* after unpacking GCC and overwrite any stale copy
of ld.mcld in GCC.  But can cause problem if we manually unpack GCC
