Is it ever possible to build libmudflap, libssp, or libgomp when 
inhibit_libc is set?
If not, is is reasonable to add a check to the top level configure to detect
situations that will cause gcc configure to set inhibit_libc and add those
libraries to either skipdirs or noconfigdirs.  (Which would be preferred?)
It looks like just a couple of lines in configure to exclude them 
automatically
if they can never build under that condition on any target.
