actually, you do: all of those are availble inside the cfarm.
I've also tested the patch on i386-pc-solaris2.11 and
sparc-sun-solaris2.11 with the native ld: no regressions in either case.
From what I can see, the handling of -Y P,* in gcc/config/sol2.h
(LINK_ARCH{32,64}_SPEC_BASE) can go as well. I'll test this, but this
is almost certainly GCC 15 material.
