[FFmpeg-cvslog] build: fix 'clean' target

[Diego Biurrun]

ffmpeg | branch: release/0.10 | Diego Biurrun <diego at biurrun.de> | Thu Jan  3 15:30:22 2013 +0100| [26b177b8f7abb2058fdd3a9142e26f118eaad294] | committer: Diego Biurrun

build: fix 'clean' target

This fixes removal of TOOLS as well as HOSTPROGS declared in the
top-level Makefile.  The clean target in common.mak needs to be
eval'd since the variables used within are reset for each library.

(cherry picked from commit 395c3feb3bb165af5760d287a9a64344b6269fe2)

Conflicts:

	common.mak
	library.mak
