Use gnu-user command line options for gcc (XCC)

We're mostly like the gnu-user config.  We don't use their gcc/config
exactly, but we take most of the parts.  We weren't taking their command
line options though, which was a problem.

If you tried to build with -rdynamic, gcc would complain.
-Wl,--export-dynamic would work, and it was just the lack of option parsing
on our part.

Thanks to James Knight for the tip to look at the opts file.

Rebuild gcc.
