i386-rtems does not build on head

After running autoconf, it fails a bit differently. Output below my 
signature.

But something doesn't seem right.  *-rtems* and other newlib targets 
have a stdint.h. 
Shouldn't libgcc-math be including the newlib cflags and possibly 
$(LIBGCC2_INCLUDES) when built?  I included LIBGCC2_INCLUDES because 
that is where gcc/config/t-rtems adds
the rtems specific newlib include directory.
