[Buildroot] libav package

[Michael J. Hammel]

I've created a libav package for 2011.02 based on the ffmpeg package. It
builds okay but I haven't tested it with any apps yet (working toward an
omapfbplay package). There is one question before submitting a patch for
it.  To get it to build I had to add the following config option:

--target-os=linux

I tried setting this to 

--target-os=$(GNU_TARGET_NAME)

but that generates linux-os which libav doesn't like.  Is it okay to
leave it hardcoded like this or is there a Buildroot variable I should
be using here?

One other question:  what's the correct command for creating the patch
for this?  I'd want to pick up both the multimedia/Config.in change and
the new directory therein.  I've created patches before but not for
adding a new directory like this.

Thanks.
