  Added:                liboil-0.3.17-amd64-cpuid.patch
  Log:
  Add upstream patch to fix CPU detection on amd64. Add prefix keywords (bug #440082, thanks to Christoph Junghans). Remove useless doc USE flag, and install docs in the location where tools like devhelp expect them. Punt .la files, and make static libs optional.
  
  (Portage version: 2.2.0_alpha142/cvs/Linux x86_64, signed Manifest commit with key CF0ADD61)
