 Summary of the bug:
 When building ffmpeg, sometimes the 'make' process fails if the option

 How to reproduce:
 Attached are all the config.* files, so anyone could reproduce this issue.
 Shortly, just build libx264 (and yasm) prior to building ffmpeg (although
 I believe this doesn't influence the issue at all, but still I'm
 describing what did I do before encountering the issue).

 Simply, run the make with, for example, an option like '-j16'.

 Latest ffmpeg from git used (08e2b0da).
