[PATCH] move sparc-sol-thread.c back into sol-thread.c.

[Rainer Orth]

Hi Joel,

I've done some digging and found that xregs on Solaris/amd64 were added
for AVX support, in Solaris 10 Update 10 apparently:

http://www.mail-archive.com/opensolaris-arc@opensolaris.org/msg01454.html

As we already found, whether or not you find ps_lgetxregsize documented
as SPARC-specific depends on the version of the Solaris 10 man pages you
are looking at, and in S11 it has been there from the beginning.  So
please adapt the comments accordingly, or even leave out the x86_64
reference altogether.

I've removed my configure hack to use sparc-sol-thread.c everywhere,
applied your patch and rebuilt gdb: it works just fine now.

Thanks.
