Some other newlib (and non-newlib) targets don't, see PR14325 and
PR16135.  There was also some issue with c99 math functions that I
have not followed closely.  Some fixes for this went in for HP-UX
and Solaris.  I don't know if newlib always provides all the math
functions libgfortran asks for.

Note that I did not mean to imply that gfortran should not be
buildable as a cross, just that I know that there used to be some
problems with this.
