ffmpeg | branch: master | Mans Rullgard <mans at mansr.com> | Fri Mar  4 19:41:33 2011 +0000| [22aebf1bfefa2347a376acea5e27dab3f1d0e08f] | committer: Michael Niedermayer

Add rule for compiling to asm

This allows commands of the form "make foo.s", which is useful
for inspecting the compiler output for debugging purposes.
