[MPlayer-dev-eng] Makefiles cleanup

[Diego Biurrun]

Here is the result of my work on the Makefiles:

before:
silver:/tmp/mplayer_r21184$ find . -regex '\(.*Makefile\|.*mpcommon.mak\)' | egrep -v 'DOCS|TOOLS|libav*|libswscale|libdha|vidix|drivers' | xargs cat | wc -l
2008

after:
silver:/usr/src/mplayer/mplayer$ find . -regex '\(.*Makefile\|.*mpcommon.mak\)' | egrep -v 'DOCS|TOOLS|libav*|libswscale|libdha|vidix|drivers' | xargs cat | wc -l
1206

Not too shabby I would say :)
