[RFC] Full float128, third iteration

I'm CC'ing the gcc list so I can get insight from people who understand correctly how static libraries should be handled by the driver...

OK, I see the same thing. It's due to the fact that when you call:
gfortran mycode.f90 -lquad -static
the linker is called with the following order for the libraries:
-lquad -lgfortran -lm --start-group -lgcc -lgcc_eh -lc --end-group
while libgfortran depends on libquad, so it should be "-lgfortran -lquad".
I'm not very knowledgeable about that, but I think what we can have the driver recognized "-lquad" and move it after "-lgfortran". That won't handle all cases (what if libquad is called something else on your computer? what if you link to a specific version, -lquad1.0? what if you link directly by specifying the archive file, /path/to/libquad.a?)
All ideas are welcome!
