No need for this unless you're using in-tree gmp/mpfr.

I've asked this before: why do you need a gdb with full debug info? If
running into problems, start with a bare-minimum configuration,
i.e. omit CFLAGS/CXXFLAGS completely. If your gcc doesn't create 64-bit
binaries by default, better use CC='gcc -m64' CXX='g++ -m64'.

If you really need another shell during the build (although the Solaris
11.3 /bin/sh, which is ksh93, should be good enough), specify
CONFIG_SHELL instead.

No need for this: the build should be fine with either Solaris ar or GNU
ar. If it's not, please file a bug report.

Again: not used in the gdb build (and not the best way for gcc,
either). Omit.

Here's your problem: this is a triple gdb knows nothing about, thus the
error when starting. The real thing is called sparcv9-sun-solaris2.11
(i.e. 2.11 instead of 11) and it's admittedly quite unfortunate that
config.guess doesn't get this right on its own. Just specify
--build=sparcv9-sun-solaris2.11; the other two (host and target) are set
implicitly from that.

I never had a need for any of those. If you do, please explain.

Again: gcc only; omit.

Use the correct triple (and omit anything not strictly necessary) and
you should be fine.
