RTL sharing bootstrap failure on sparc-sun-solaris2.10

(Sorry, first one bounced from gcc@ because it was over 400k)

Hi Jan,

On sparc-sun-solaris2.10, I'm getting new bootstrap failures in stage2
complaining several times about rtl sharing.  I've included four .i files
for modules that ICEed during stage2, and the cc1 invocations below.

Would you please take a look?

		Thanks,
