clang-cross: Create <cross>-clang binary copy instead of symlink

Browse Source 
With clang cleanup in [1] we ended up removing this logic, which
is still required.

This ensures that search path for subsequent tools e.g. linker
assembler are searched in the same dir where <cross>-clang is
installed. If its a symlink to ../clang then the reference
installation dir is ../ and all cross-tools are not there
so clang will fail to find assembler/linker from cross staging
area and use /usr/bin/ld or /usr/bin/as  which we do not want
