libgcc sparc-rtems config on gcc head

[Joel Sherrill]

Hi,

The sparc libgcc configure magic looks very
different on the head versus 4.6.  sparc-rtems4.11
was not building because it was missing crti.

In 4.6, we got the makefile stub from sparc/t-crtin
but that no longer exists.  It looks like the
rules are on t-sol2 now.

I made this change to libgcc/config.host and
it is getting further.  Does this look like
what the intended change?
