862c35457d Fix build of glibc 2.29 on systems with obsolete host programs
- 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.

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.

1d724767bd config: Add package versioning flexibility
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

Alexey Neyman
7bcf18bfab Determine whether -E/-r option selects extended regexp
... 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.

ee1c04378c debug/gdb: restore comments
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.

488b27f58b Partially revert 6f8e89cb5c.
The referenced commit replaced 'make' with '${make}' everywhere. This is
wrong for at least the utilities that we may build as companion tools
(make, libtool): this will always invoke the version detected by configure
by supplying the absolute path. In other words, the wrappers in
.build/tools/bin are not fallbacks - they are either temporary (in case
a respective companion tool is built) or permanent redirectors.

This is the reason why the PATH= has .build/*/buildtools/bin at higher
precedence than .build/tools/bin; the latter has the versions detected by
configure and the former has the versions built as companion tools.

Revert the rest of the gang (grep/sed/...) for consistency. After all,
we may decide to supply some of them as well (awk, for instance).

5d5465307b debug/gdb: properly link with expat
This patch fixes libexpat detection for gdb-native and
gdb-cross static builds.

For gdb-native build configure should not touch system
/usr/{lib,include} directories while looking for libexpat.
To fix this we pass --without-libexpat-prefix flag
to configure script.

For gdb-cross build configure is allowed to investigate
system /usr/{lib,include} directories, but it does not
hurt to disable this behavior. In this case configure
falls back to -lexpat, which works as expected.

Previous fix for cross-gdb broke powerpc-unknown_nofpu-linux-gnu which

multiple consecutive spaces; see the comment in 300-gdb.sh.

62d357d3c0 Unbreak static cross-gdb.
GDB's configure mishandles the libexpat.{so,a} libraries when it is
given -static in CFLAGS AND --with-libexpat-prefix in configure's args:
it checks for <prefix>/lib/libexpat.so and finding that, attempts to
link it as `gcc -static .. conftest.c <prefix>/lib/libexpat.so`; this
obviously fails (.so cannot be statically linked), so configure assumes
libexpat is unusable. Thus, --with-libexpat-prefix is dangerous and
should be avoided; instead, configure should find the libraries via the
supplied CC/LD definitions.

We check for apps:

* make
* sed
* grep
* awk
* libtool/libtoolize
* install

...during configure. Our scripts should be consistent about using the
variables that define where the found tool was found.

Of course, we do hard-link these tools in buildtools, but that should be
a backup for the components we are building. Our scripts should always

81328ed1cb xtensa: add support for the configurable Xtensa architecture.
The Xtensa processor architecture is a configurable, extensible,
and synthesizable 32-bit RISC processor core. Processor and SOC vendors
can select from various processor options and even create customized
instructions in addition to a base ISA to tailor the processor for
a particular application.

Because of the configurability, the build process requires one additional
step for gcc, binutils, and gdb to update the default configuration.
These configurations are packed into an 'overlay' tar image, and are
simply untarred on top of the default configuration during the build.
