Patch by Nathan Mentley:

Browse Source 
* Added a few header files in headers/posix/arch that'll allow for an x86_64
  haiku target to be compiled. fenv.h is src/lib/msun/amd64/fenv.h from
  freebsd.
* configure: Added support for x86_64 arch when running
  build_cross_tools_gcc4.
* config[_build]/HaikuConfig.h, BuildSetup: Added x86_64 recognition.
