This warning is designed to catch likely vulnerabilities in code run
under memory protection -- allowing execution from memory which is
writable. However, embedded arm systems frequently require placing code
in RAM, for performance or functionality reasons. Disable the warning
that recent versions of binutils has added.

The bionic libc support was out of date and relied on downloading
binaries from the internet. It was already marked as obsolete. Now that
the 1.25.0 release is out it can be completely removed.

Support for bionic was dropped by GCC some time ago. There are patches
for older GCC versions but those are difficult to maintain and the
version of the android-ndk they support is of little use. Mark all of
the existing bionic support as obsolete so it can be removed after the
next release.

Starting with GDB10, it requires support for std::future<> in the
compiler. Such support has not been available on some architectures
until GCC9 (see PR 64735). I haven't determined the exact list of
affected architectures, so decided to make it a broad dependency: for
GDB10+, you need GCC9+.

Restrict kernel to 5.11 and below (support for this arch has been
dropped in 5.12); rename the sample to match its name as printed by
`ct-ng show-tuple` (otherwise, `make saveconfig` does not update the
sample's configuration).

*-moxie*: DTC_VERBOSE is a wobbler, it depends on whether dtc is enabled
on the host machine (if dtc is installed, DTC defaults to 'n' and hence
prevents DTC_VERBOSE from appearing at all). Remove the option from
config file so that its value reverts to the default.

Run samples through upgrade and fix accumulated breakages:
*-centos6-*: After 2.12.2 retirement, the samples selected most recent
glibc (2.34) which also forced kernels 3.2+. Revert to 2.12.1 and
2.6.32.71, respectively. Interestingly, 2.12.1 was marked as being used
in CentOS6, but the samples selected 2.12.2. Anyway, CentOS6 is EOL now
and glibc 2.12 is going to be marked obsolete, and retired soon.
arc-*: Make TARGET_VENDOR match the sample's name; otherwise `ct-ng
saveconfig` places the config file into a different location.
Fix 'savedefconfig' which was not saving the configuration file version
(CT_VCHECK was set to 'load' after CT_LoadConfig call).

... and the code dependent on them, after the latest wave of obsolete
package removals. This concludes the glorious history of the original
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.

GCC 4.8 and its prerequisites have been removed by 04dce680, 41d4583a
and e4221734; as a result, 4.8-based version of gcc-oracle became
unbuildable (no valid versions for the prerequisites).
Update the samples to use 4.9.4; which however fails to build on a modern
host GCC. Build fix backported to gcc-4.9 and gcc-5 versions.

From GCC's standpoint ARC's multilib items are defined by "mcpu" values
which we have quite a few and for all of them might be built optimized
cross-toolchain.
From Glibc's standpoint multilib is just multi-ABI [1] and so very limited
versions are supposed to co-exist (e.g. arc700 & archs).
Here we force Glibc to install libraries in GCC's multilib folder to create
a universal cross-toolchain that has libs optimized for multiple CPU types.
But note we only need to mess with installation paths in case of real
multilib, otherwise we keep default "lib/" paths so that GCC finds default
(the one and only) libs where it expects them to be.
Also here we add a sample which allows to build universal Glibc Linux
toolchain for ARC.
