toolchain.eclass: fix warnings when progs are linked

When gcc installs programs into BINPATH, it sometimes links them so that
the $CHOST-xxx and xxx progs are the same.  The logic to standardize the
naming in BINPATH then triggers a warning as they're the same file.

Manually delete the target before running the mv to avoid that business.
