Comment:

 jeremyhu@ committed an additional clang fix in r117575 but that doesn't
 help this issue either.

 The issue was recently discussed (heatedly) upstream
 [https://mailman.videolan.org/pipermail/x264-devel/2014-February/010371.html
 Failure to build x264 with ASM on i386].

 The closing guidance from the upstream developers is this:
  * give up on --enable-pic as x264's asm optimizations for i386
  wouldn't be PIC anyway (even if you didn't get this compilation
  error) and will have textrels;
  * give up on asm and use --disable-asm if you for some stupid reason
  no matter what need PIC;
  * give up on i386 and build for x86_64 if need both PIC and asm.

 I don't see any way around the situation either but, of course, I would
 defer to anyone who has a better idea.

 In the meantime, in the current state of the port, it is obvious that +asm
 is incompatible with +universal due to i386 issues.  +universal builds
 successfully without +asm and this is the current default.  +asm builds
 fine for x86_64 without +universal, again the default.

 I also note that this is not just a Mavericks issue.  I can reproduce the
 problem on ML as well.

 For now, don't use +asm and +universal together.  If you want +asm, use
 the default build. I am marking variant +asm as conflicting with
 +universal.
