Subject: [gentoo-commits] gentoo-projects commit in pax-utils: Makefile
Date: Wed, 22 Oct 2008 15:31:05 +0000 [thread overview]
Message-ID: <E1Ksfft-0004uu-T6@stork.gentoo.org> (raw)

Modified: Makefile
Log:
Improve Makefile to avoid relinking all targets when changing one tool.
With these changes, editing scanelf.c won't trigger a new build of
dumpelf and pspax, since each target depends only on those object
files it actually uses.
