scripts: always create lib32 and lib64 symlinks
Unconditionally create the lib32 -> lib/ and lib64 -> lib/ symlinks.
This is reportedly a fix to build a toolchain for a 32-bit target on
a 'pure' 64-bit host (eg. on Fedora FC12, host libs are in lib64/,
and there is no lib -> lib64 symlink, as we can see on other distors,
as Debian). As gcc only puts static host lib in lib64/ (along with
target files in subdirs), we can safely create the symlinks.
Also note that the symlinks are summarily removed at the end
of the build.
