ffmpeg | branch: master | Diego Biurrun <diego at biurrun.de> | Wed Sep  5 20:49:28 2012 +0200| [a7329e5fc22433dfeaf7af22fb40fe3cada21385] | committer: Diego Biurrun

x86: get_cpu_flags: add necessary ifdefs around function body

ff_get_cpu_flags_x86() requires cpuid(), which is conditionally defined
elsewhere in the file.  Surrounding the function body with ifdefs allows
building even when cpuid is not defined.  An empty cpuflags mask is
returned in this case.
