[RFC/PATCH] Avoid TAGS/tags warning from GNU Make

From: Johannes Schindelin <redacted>
Date: Thu, 22 Oct 2009 19:04:17 +0200

MinGW make considers the TAGS and tags targets to refer to
the same file:

 Makefile: warning: overriding commands for target `TAGS'
 Makefile: warning: ignoring old commands for target `TAGS'

Suppress both targets on that platform.

This is kind of ugly; I hope there is a better way.  Maybe mingw
make ought to special-case the TAGS name, since this has come up in
other projects[1], too.
