[Ian Lance Taylor <iant@google.com>] PATCH RFA: Remove prev-DIR/Makefile to force reconfigure

[Ian Lance Taylor <iant at google dot com>]

A ping for this simple patch.  Paolo said it looked good to him, but
that was before he became a build system maintainer.  Paolo, do you
want to approve it for real now?

Thanks.

Ian

There is code in the top level configure.in file to force
subdirectories to be reconfigured by removing DIR/Makefile.  That code
handles stage*-DIR.  However, if you have completed a bootstrap, the
directories will be named stage1-DIR and prev-DIR.  In order to
properly force a reconfigure, prev-DIR/Makefile needs to be removed
also.

This patch does that.  Tested by running configure.  OK for mainline?
I will commit to src after approved for gcc.
