Subject: toolchain.eclass: fix warnings when progs are linked
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ee120105fcf78fec48e6b1860fee06b729d7d86f;p=gentoo.git

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.
