PCH tests fail on sparc-sun-solaris2.7

Geoff - as seen here:
http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg00571.html
pretty much all of the PCH tests fail on sparc-sun-solaris2.7.

Looking in the log file, all of the error messages look like this:

 > gcc.dg/pch/global-1.c:-71: sorry, unimplemented: had to relocate PCH
 > gcc.dg/pch/global-1.c:-71: internal compiler error: Segmentation Fault

(Sometimes the line number was -70 or -72 for the various other tests.)
The g++ tests fail the same way.

I looked in gcc.dg/pch/pch.exp and guessed that I had to generate the
PCH file by hand and rename it to *.hp.pch.  (Is that right?)  Then I
ran cc1 on global-1.c under gdb and got an invalid memory reference as
you can see below.  I'm not sure what I need to provide for you to
reproduce it in a cross config.  PCH perhaps requires us to update our
bug reporting instructions slightly?
