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
versions of strace bundle the kernel headers which cause build errors
such as:

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++.

- Force building make as a companion tool if host make is older than
4.0 (CentOS 7 currently has 3.82)
- Disable 2.29 as a choice if host python is older than 3.4
(CentOS 7 has 2.6 unless python from EPEL is installed)
- Python2 emits its version information to STDERR. Ugh.
While there, also use the detected host Python for GDB configuration.

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.

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.

Some users (like myself) may want to omit the crosstool-NG version
from the binaries' versioning output, as it can be incredibly long
and not too helpful. Add a config option to disable it. The possible
combinations are as follows:
- crosstool-NG version (default)
- crosstool-NG version - custom toolchain ID
- Custom toolchain ID
- No crosstool-NG version OR custom toolchain ID

... and then use the right option. See the note in scripts/functions
on where we should use ${foo} and where just 'foo'; this boils down to
whether we can expect the build tools override to be in effect (e.g. in
the actual build scripts) or not (i.e. outside of scripts/build).
While running in scripts/functions, or in scripts/crosstool-NG.sh the
build tools override directory (.build/tools/bin) may have not been
set up (yet, or at all).
Also, modify the installed scripts (populate, xldd) accordingly.

- installs headers, without them it does not make sense to install a

The correct solution was checked in to strace GIT; will be part of the
next release. Backport patch to 4.10..4.15, and remove the workaround
from 500-strace.sh. Versions 4.9 and older should build fine even
without the workaround (they would be picking up wrong definitions,
but they need different patch and I don't feel like spending any time
on these versions).

debug/gdb: properly link with expat
|

There are two separate issues with gdb configure usage:
1) inspecting build system libraries while cross-compiling;
2) preferring a shared library over static one.
The first usage issue is described and fixed now.
The second issue was described but the notes were removed
for some reason. This patch restores those notes.
