[rfc] LINUX/sparc64 configury

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

The attatched adds sufficient configury to GDB for it to build a very
basic GNU/Linux/sparc64 GDB.  It doesn't work:

$ ./gdb gdb
GNU gdb 5.0

This GDB was configured as "sparc64-unknown-linux-gnu"...
Setting up the environment for debugging gdb.

I'm really only interested in comments on my choice of file names.  I
think they are even 8.3 safe! :-)

More patching/merging will obviously need to follow.  If anyone wants to
help, see Jakub's ``[PATCH] Sparc Linux stuff'' posting for my source of
patches.

PS: So Kevin, how soon can we get the abort() patch in :-)
