Picolibc needs two additional gcc build options so that libstdc++
works correctly. When building picolibc as a companion library, those
are added in do_cc_libstdcxx_picolibc, but when built with picolibc as
the main C libary, those need to be added in the main GCC build.

There was a typo in the original commit which used "zlib" instead of
"zstd". The checksums remain the same.

We've been carrying around this patch for ages. It was first added in
commit 42e908c4 ("libc/glibc: workaround for autoconf'ed define of
caddr_t") and ported to glibc-2.13 in commit de6b6733 ("libc/glibc: add
patch to avoid caddr_t redefinition"). It has been ported to every new
version of glibc ever since.
It's not immediately obvious that the original problem still affects
modern glibc versions. If there is a problem it hasn't been reported to
the glibc maintainers in the 12 years since it was first seen. It could
be that ct-ng is unique in the way we support canadian builds or that
there was another fix for the same problem applied upstream sometime in
the last 12 years.
Drop the patch now to stop in being propagated blindly to new glibc
versions. Doing it as a separate commit (as opposed to dropping it in
the previous commit which bumped the version) allows the decision to be
documented and if this turns out to be wrong it can be easily reverted.

libgccjit is still under development and, despite its name, may also be used for
ahead-of-time compilation.
Documentation can be found on the gcc website:
https://gcc.gnu.org/onlinedocs/jit/internals/index.htmlhttps://gcc.gnu.org/wiki/JIT
With this change it's possible to enable the building of the libgccjit. It's
enabled as a language (with --enable-languages=jit) even if not a language
frontend at all.
The main changes are related to the requirement of having everything host side
built as Position Independent Code (PIC) with --enable-host-shared. GCC has the
needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when
built "in-tree", which is not the case with crosstool-ng (see
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0)

--enable-e500_double was valid but strange (the correct form is
--enable-e500-double). -Wa,-me500x2 was also misleading, it is
equivalent to Wa,-me500. --enable-e500x2 --with-e500x2 did nothing as
they aren't used by the binutils configure script. Finally passing
-mfloat-gprs=double in CFLAGS is unnecessary because this is the default
when using -mcpu=8548. Correct these in the sample config.
Fixes#1867

BPF is a virtual machine and associated ISA that resides in the Linux
kernel. Initially intended for user-level packet capture and filtering,
BPF is nowadays generalized to serve as a general-purpose infrastructure
also for non-networking purposes.

Reverts the changes introduced to `m4/ax_with_curses_extra.m4`
in 59b664806c,
which seem to make `cofigure` look only for `ncursesw/panel.h`
and not consider `panel.h` as a candidate,
thus causing `./configure` to fail with
"error: panel library not found" on systems
(such as Arch Linux) where ncurses headers
are not put under the `ncursesw/` directory.

Brings in the following changes
- Fix a bug when getting a gzip header extra field with
inflateGetHeader(). This remedies CVE-2022-37434.
- Fix a bug in block type selection when Z_FIXED used. Now the smallest
block type is selected, for better compression.
- Fix a configure issue that discarded the provided CC definition.
- Correct incorrect inputs provided to the CRC functions. This mitigates
a bug in Java.
- Repair prototypes and exporting of the new CRC functions.
- Fix inflateBack to detect invalid input with distances too far.
Mark zlib-1.2.12 as obsolete.
