58c347c781 gdb: Realy decouple building of native/target GDB & gdbserver
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".

4a8f7ff12b gdb: Enable TUI for full target/native GDB
Since we have curses built for target anyway now, why don't allow
users to use very convenient pseudo-GUI operating mode?

And while at it, there's no use of TUI in naturally headless gdbserver.

5463ab4bf6 gdb: Add gdb-10.2
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.

2baacbfe36 gdb: Don't mess with gdbserver config permissions
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 ;)

Similar to commit ca45a8f9 ("Add -D__GLIBC__ to target CFLAGS") newer

041427aec9 Enable static libgcc when CT_GDB_NATIVE_STATIC_LIBSTDCXX is set
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++.

d573c15758 Use 'chmod a-x' instead of 'chmod -x'
There is a subtle difference when executable bit is a part of the umask.
And at least some versions (Debian/stretch) fail if the resulting mode
would've been different if not for the umask setting.

Fixes #998.

Although, with such chmods/umasks it is likely that some package installation
will break anyway. But I'll leave it until somebody complains.

70a1584e15 Fix variables passing to gdb configure scripts
These changes mainly fix static linking errors when building static
native gdb and gdbserver (tested with gcc 7.2.0 + uClibc-ng 1.0.27 +
binutils 2.29.1 for MIPS):

[ALL  ]    .../lib/libstdc++.a(eh_throw.o): In function `__cxa_throw':
[ALL  ]    (.text.__cxa_throw+0x64): undefined reference to `_Unwind_RaiseException'
[ALL  ]    (.text.__cxa_throw+0x6c): undefined reference to `_Unwind_RaiseException'
[ALL  ]    .../lib/libstdc++.a(eh_throw.o): In function `__cxa_rethrow':
[ALL  ]    (.text.__cxa_rethrow+0x78): undefined reference to `_Unwind_Resume_or_Rethrow'
[ALL  ]    (.text.__cxa_rethrow+0x80): undefined reference to `_Unwind_Resume_or_Rethrow'
...

The problem is in mixing of CPP, CC, CXX, and LD with CPPFLAGS, CFLAGS,
CXXFLAGS, and LDFLAGS before passing to configure scripts.
gcc is sensitive to argument order and the scripts are normally responsible
to combine the variables in a proper way.
