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.
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.

The FTP protocol is getting long in the tooth, and we should emphasize
HTTPS where that is available. This patch changes various gcc.gnu.org
URL's to instead use HTTPS.
For instance, kernel.org shut down FTP access in 2017, with the
explanation:
- The protocol is inefficient and requires adding awkward kludges to
firewalls and load-balancing daemons
- FTP servers have no support for caching or accelerators, which has
significant performance impacts
- Most software implementations have stagnated and see infrequent
updates

Bump the minimum MPFR version to 3.1.0, released 2011-10-03. With this
requirement one can still build GCC with the operating system provided
MPFR on old but still supported operating systems like SLES 12 (MPFR
3.1.2) or RHEL/CentOS 7.x (MPFR 3.1.1).
This allows removing some code in the Fortran frontend, as well as
fixing PR 91828.

The new arm-uclinuxfdpiceabi target behaves pretty much like
arm-linux-gnueabi. In order to enable the same set of features, we
have to update several configure scripts that generally match targets
like *-*-linux*: in most places, we add *-uclinux* where there is
already *-linux*, or uclinux* when there is already linux*.
In gcc/config.gcc and libgcc/config.host we use *-*-uclinuxfdpiceabi
because there is already a different behaviour for *-*uclinux* target.
In libtool.m4, we use uclinuxfdpiceabi in cases where ELF shared
libraries support is required, as uclinux does not guarantee that.

gdb should normally not be linked with -static-libstdc++. Currently
this has not caused problems, but it's incompatible with catching an
exception thrown from a shared library -- and a subsequent patch
changes gdb to do just this.
This patch adds a new --with-static-standard-libraries flag to the
top-level configure. It defaults to "auto", which means enabled if
gcc is being built, and disabled otherwise.

Oops, I forgot to update the MAINTAINERS file a couple of months ago,
when the address there stopped working.
Honestly, I haven't really had much involvement with the frv, mn10300
or sh ports for almost 15 years, so I wouldn't mind if someone else
stepped up and took over, but until someone does, I don't mind
reviewing the occasional patch, so it's best if it can reach me ;-)

The code that checks if an auto-increment from i0 or i1 is not lost is
a bit shaky. The code to check the same for i2 is non-existent, and
cannot be implemented in a similar way at all. So, this patch counts
all auto-increments, and makes sure we end up with the same number as
we started with. This works because we still have a check that we
will not duplicate any.
We should do this some better way, but not while we are in stage 4.
