x264 | branch: master | Steven Walters <kemuri9 at gmail.com> | Wed Aug 19 16:18:36 2009 -0700| [816a3008a8fcb70b642dc8670426ad28d59b7b9a] | committer: Jason Garrett-Glaser 

Fix a bug in checkasm and two OSX fixes
MC chroma checkasm test could crash in some situations
Remove -lmx, as it's not needed and the iPhone doesn't have it.
Remove unused sqrtf emulation; it breaks if math.h is included.
