Summary: Support for build with --enable-64-bit on Solaris with gcc

Initial Comment:
Attempt to configure current Tcl with --enable-64bit on
Solaris sparc when using GCC as compiler results in
warning:

"64bit mode not supported with GCC on $system"

but GCC support building of 64-bit apps on Solaris
since release 3.3 - for more than two years now. 

It seems that it is time to add support for building
64-bit tcl with GCC. 

Following patch to tcl.m4 adds support for building 64
bit tcl with GCC.  It is made against 8.4.7 release
sources, but applies cleanly to the current CVS version
as well.

Resulting 8.4.7 executable passes all tests.

Suspicious place in this patch is unconditional adding
-R /usr/local/lib/sparcv9 option to linker. It is
required because GCC-compiled executables typically
need shared libgcc library.
