Well, its part of gcc, not something meta-intel is patching in and its
a standard which other arches can implement, maybe in their own library
so I believe the recipe is the better place for this to live. I just
copied the description from the code iirc.

Incidentally, this fails to build on musl so I've just disabled it on
musl for now.
