I think this patch is a good fix.  I (obviously) don't favor reverting
the previous patch because that would re-break the Fortran build on MIPS
bare-metal cross compilers (or any compiler where a linker script is
needed).  Any 'proper' fix should address libstdc++, libjava, and other
libraries as well as libgfortran and I don't know what a cleaner fix
would be.  In fact I would say the other libraries should consider using
this fix.  The only reason they don't run into this problem too is that
they don't depend on any long double functions or any other functions
that are optionally built by newlib.

I will test this patch on my targets and make sure it works for me, but
I don't see why it would not.
