These look a bit special/weird, especially ac_cv_fcntl=yes. Normally
for functions, the cache variable is named ac_cv_func_<function>, and
the checks don't need to pre-seed cache variable values.

Can you add a comment on top of this line that explains why those two
values need to be passed? Or at least, it should be explained in the
commit log (but a comment in the code is better IMO).

Thanks!

Thomas
