proposed patch

The patch checks if the directory spec_machine (e.g. i686-linux), i.e. the
directory where all the target libraries and assorted stuff are,
can be found without following symlinks; if that is the case, it assumes that
the other pieces of the toolchain should also be found
without trying to resolve symlinks for generating the prefixes.
