[x264-devel] x86inc: only define program_name if the macro is unset.

[Diego Biurrun]

x264 | branch: master | Diego Biurrun <diego at biurrun.de> | Wed Oct 31 12:23:54 2012 -0700| [f418867a8b76f31acf3a965eed34c5587294e948] | committer: Jason Garrett-Glaser

x86inc: only define program_name if the macro is unset.
This allows overriding the value from outside the file.
This can be useful if x86inc.asm is used outside of x264.
