Solaris 64-bit support is in 2.95!

[Richard Shih-Ping Chan]

For those of you looking for Solaris 64-bit support
the target is there in gcc 2.95 as sparcv9-sun-solaris2.7.

As we know some people have raised the incompleteness
of this target so YMMV.

Also to get it to work you may have to build it as a cross compiler
first. I.e., use a sparc 32 compiler to build a sparc32 to sparc64
cross, then build a native compiler.
