One possibility would be to change libatomic/fenv.c to include a local 
atomic-fenv.h (for example) header instead of <fenv.h> (which would no 
longer need a configure check), so that if the generic file is OK for an 
architecture then that architecture would provide an atomic-fenv.h header 
in libatomic/config, defining the macros to correspond directly with the 
bits from the relevant status register (and any architecture without 
support would get a dummy atomic-fenv.h header not defining any of the 
macros).  That way, the hook doesn't need any OS-dependence.
