[Patch] New sparc targets. 2.95?

[Jonathan Larmour <jlarmour at cygnus dot co dot uk>]

None of the sparc targets sparclite-elf, sparc86x-aout and sparc86x-elf
appear to be available in egcs, even though all the sparc.c/sparc.md support
is present.

This is simply an oversight from when stuff was being contributed by Cygnus,
which the attached patch fixes. I have not given a patch for "configure"
itself - it seems almost as pointless as ChangeLog patches, so whoever
applies the patch should run autoconf before committing.

Since this patch is effectively orthogonal to the operation of the rest of
egcs, I suppose there's no chance it could slip into 2.95? Unlikely I know,
but I thought I should ask...
