There was general agreement last November that we would move to allowing
C++11 features to be used in GCC 11; this patch implements that direction.

We recently rearranged the gdb source tree to move a common library
and gdbserver to the top-level. This made the build more uniform and
also a bit faster (due to sharing of built objects).
This patch re-syncs these changes the top-level configury back to gcc.
ChangeLog:
* configure: Rebuild.
* Makefile.in: Rebuild.
* Makefile.def (gdbsupport, gdbserver): New host modules.
(configure-gdb): Depend on all-gdbsupport.
(all-gdb): Depend on all-gdbsupport, all-libctf.
* configure.ac (host_tools): Add gdbserver.
Conditionally build gdbserver and gdbsupport.

* configure.ac: Build libgomp by default for amdgcn.

I left SiFive a bit more than three months ago, and while I sent out a message
saying I was going to updated my email address I neclected to actually do so.
I'm moving to my personal email address to avoid the need to do this again.

This un-documents constraints that cannot (or should not) be used in
inline assembler. It also improves markup, and presentation in general.
More work is needed, but gradual improvement is easier to do.
* config/rs6000/constraints.md: Improve documentation.

* doc/md.texi (PowerPC and IBM RS6000): Improve documentation.
