to target Oracle Linux 7.9:
Binutils 2.27-44.base.0.400
GCC 4.8.5-44.0.5
glibc 2.17-317.0.3
UEK5/u4 4.14.35-2025.400.8
Sample configuration files are provides for the following triplets:
arm-ol7u9-linux-gnueabi
arm-ol7u9-linux-gnueabihf

Currently the help for LOCAL_PATCH_DIR did not specify the tree layout
of custom patches directory. This commit adds such explanation.
For example, the bundled patches for GCC are placed under
packages/gcc/<gcc-version>, thus custom (local) GCC patches should be
placed under $LOCAL_PATCH_DIR/gcc/<gcc-version>.

Make --enable-obsolete-rpc conditional on !CT_GLIBC_2_32_or_later as
it's been removed from that version on.

When building powerpc64+glibc-2.32 we see the following error:

This seems to only trigger for powerpc64. Other architectures build
cleanly. For now avoid specifying -Werror for powerpc64+glibc-2.32.

This adds support for using picolibc instead of newlib on embedded
systems.

GLIBC 2.31 needs --with-cpu=ultrasparc for both 32/64-bits now, and
--with-cpu only sets the CPU model for the "primary" bitness.

Fixes: #1210
Per the release notes for the GNU C library 2.28[1] make 4.0 or newer is
required. Previously the logic was applied to glibc 2.29 or newer.

While we may use build machine's library when building a simple cross,
we won't have it for the host machine in a canadian build. Until there
are separate selectables for the build/host components, just build our
own local zlib.

- 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.

Slightly rework config version detector to catch the case where neither
CONFIG_VERSION/CONFIG_VERSION_CURRENT is defined in the config file.
Add olddefconfig and use it after the upgrade.

Also, unmark the moxie-elf as broken: the ld scripts installed by newlib
can be found by the compiler and can link the binaries. Why the default
script is broken is not ct-ng's problem...
