The native gdb needs the version of libexpat built for the target. On
some systems gdb's configure will find the one from the build machine.
Use --with-expat= to point at the correct one for the target.

Starting from GDB 11.x, gmp is needed as a dependency to build full gdb.
And by default build system of native GDB will try to link with libgmp
of the build host. And to make sure that doesn't happen we need to
specify location of the target's sysroot so that library search starts
from there. Which we do in that change.
Fixes [1] & [1].

As of version 13.x GDB uses libtool for linking instead of g++ these
take different arguments for static linking. Commit 6146b5a6 ("use
-all-static when building a static gdb") attempted to deal with this but
had the effect of causing older GDB versions to fail to build
statically. Add a new internal flag GDB_CC_LD_LIBTOOL and use this to
decide whether to pass `-static` or `-all-static`.

gdb is linked with libtool, which has a different meaning
for -static, and -all-static must be used to get a static executable.
The binutils build script already uses this option for static builds.
Also remove unnecessary -static from cflags for the gdb build.

If static cross GDB configuration is selected, cross GDB will be linked
statically with std c++ library, because there is no separate option for
static std c++ library for cross GDB.
The use of not existing variable CT_GDB_NATIVE_STATIC_LIBSTDC has been
replaced with CT_GDB_NATIVE_STATIC_LIBSTDCXX.

Use a relative path for include directory if gdb or gdbserver
is being built and installed for a target. Otherwise headers
are installed in ${destdir}${CT_HEADERS_DIR} - a concatenation
of ${destdir} and an absolute path to sysroot's include directory.
As a result debug-root may contain wrong paths for includes.

Add duma 2.5.21 and mark 2.5.15 as obsolete. While we're at it use the
versions hosted on github which requres new checksums for the 2.5.15
version because the generated tarballs are different.
It appears we don't need any of the patches we've been carrying for the
older version but we do need to pass CC_FOR_BUILD in addition to HOSTCC.
When 2.5.15 is removed we can drop HOSTCC (and DUMA_CPP, DUMA_SO).

uClibc (non-NG) with lots of kludges removed.
There was a choice here, whether to call the resulting libc "uClibc" or
"uClibc-ng". I opted in favor of giving uClibc-ng the recognition it
deserves, although it had some ripple effect in the ct-ng code.

Now that the oldest supported version of gdb is 7.11.1 we can make some
parts of the build unconditional and remove the associated config vars.

Back in the day gdbserver was treated as a subproject of GDB and
even was located in "gdb/gdbserver" and so to build gdbserver we had
to go into "gdb/gdbserver" and there run configure. That way full GDB
was out of the picture.
Now starting from GDB 10.1 where gdbserver was promoted to the top-level
we're supposed to run top-level's configure script for all the tools
provided by the unified binutils-gdb tree.
That said if we only want to build gdbserver (and that's what we
want since we build one tool at a build step) we have to be explicit:
----------------->8----------------
--enable-gdbserver --disable--gdb
----------------->8----------------
Ah, and so far we used to build full native GDB when only wanted gdbserver
if it was GDB v10.x ;)
Ironically full native/target GDB also enabled gdbserver by default so
we need to also disable it explicitly with "--disable-gdbserver".

Since we have curses built for target anyway now, why don't allow
users to use very convenient pseudo-GUI operating mode?

In GDB 10.x gdbserver was promoted to the top-level folder,
see https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=919adfe8409211c726c1d05b47ca59890ee648f1
Which means it is no longer a subfolder in "gdb" and so we have to
build gdbserver now exactly in the same way as normal native GDB.
One interesting detail is gdbserver doesn't need to deal with target
description in .xml so it doesn't depend on libexpat on target,
thus we need to move libexpat explicit selection from do_gdb_backend()
to its callers when building native [full] gdb as well as cross-gdb
for the host.

[cp: support old/new layout, regenerate patches]
Signed-off-by: Chris Packham <judge.packham@gmail.com>
Some really old GDB releases did have gdbserver's configure
script w/o execution permissions, so there was a need in the fix.
As per Yann most likely it could have been true for GDB versions in
between v5.3 & 6.6. Moreover it could have been fixed on re-release
of GDB tarballs done in 2011, see [1].
And given we no longer support such old GDB versions in CT-NG
(as of today we have 6.8 - 9.2, moreover it's not clear which of
6.8-7.x versions are still being actively used) we'll revert that old hack
for now in a hope that it won't hurt anybody.
Though if somebody sees that problem again
we'll be able to revert this again ;)

This commit updates the GDB build script to specify `-static-libgcc`
when `CT_GDB_NATIVE_STATIC_LIBSTDCXX` is enabled. Both libgcc and
libstdc++ are considered to be part of the "standard libraries," and
should be specified by the same flag (the configuration symbol could
potentially use a better name and/or further indirection).
This also semantically aligns the `CT_GDB_NATIVE_STATIC_LIBSTDCXX`
with the equivalent GCC configuration `CT_CC_GCC_STATIC_LIBSTDCXX`,
which also enables static linking of both libgcc and libstdc++.
