This seems to be ok for the ffs function, the others are not part of the
standard C library.

I'd look for for the non-SMP implementation and start from there, they
should be somewhere in gnumach sources.

Also it seems that local_bh_count and local_irq_count are used only in
the Linux-based drivers, so maybe you can look to the SMP-aware
implementation in Linux (or #define the functions as empty macros if
they are not strictly needed..)
