How about making crc32c an inline function then?
On processors that have this feature, this compiles to that single
instruction, plus whatever setup it needs. Nice and efficient.
On other processors, either inline the algorithm or inline
a call to an out of line function, depending on how bulky this is.

Similiar for any other functions that may or may not have hw support.
