a7329e5fc2 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.

f6fbce761e x86: Drop CPU detection intrinsics
Now that there is CPU detection in YASM, there will always be one of
inline or external assembly enabled, which obviates the need to fall
back on CPU detection through compiler intrinsics.

05e209c04c Allow use of strncpy()

A blanket ban forces more convoluted solutions to be used in those

on the first fields, the keys from the shorthand list are
assumed, in order.
