If you have a portability issue where they're not present on your platform, please define them on your platform instead of making people use some other function.
In other words, I think the preference is to use the ffs/ffsl names everywhere, and never call "_mesa_ffs". On platforms that don't natively support ffs, Mesa would provide the implementation of ffs.
