3.0.1 PATCH: Avoid non-PIC code in boehm-gc for Solaris 2/Intel


An initial attempt to bootstrap GCC 3.0 on Solaris 8/Intel with
--enable-libgcj failed when trying to link the shared libgcjgc:

ld: fatal: relocations remain against allocatable but non-writable sections

I.e. the current code required text relocations, making the text section
non-sharable.  The patch below fixes this.  Bootstrapped with no
regressions on i386-pc-solaris2.8.

Ok for branch and mainline?
