initial patch

The patch above worked for me.  It allowed gcc mainline bootstraps with the 
patched gas and Sun ld to complete without regressions on i386-pc-solaris2.[89]
and i386-pc-solaris2.1[01], fixing the current TLS LD related testcase
failures.

It currently lacks testcases, and it appears that it cannot be installed on
it's own: the resulting gld knows enough about the new relocs for the link
tests
in gcc/configure.ac to succeed incorrectly, breaking the build later on.

I'll work on the ld side (PR ld/12996) later, but had a very hard time
producing
anything even remotely useful when I last tried.
