Support for these was added by the following commits:

The unicore32 port do not seem maintained for a long time now, there is no
upstream toolchain that can create unicore32 binaries and all the links to
prebuilt toolchains for unicore32 are dead. Even compilers that were
available are not supported by the kernel anymore.
Guenter Roeck says:
I have stopped building unicore32 images since v4.19 since there is no
available compiler that is still supported by the kernel. I am surprised
that support for it has not been removed from the kernel.
Remove unicore32 port.

I was manually editing the arch-support.txt for eBPF-JIT, when I
realized the refresh script [1] has not been run for a while. Let's
fix that, so that the entries are more up-to-date.

powerpc architecture (both 64-bit and 32-bit) supports stack protector
mechanism since some time now [see commit 06ec27aea9fc ("powerpc/64:
add stack protector support")].
Update stackprotector arch support documentation to reflect the same.

HAVE_CC_STACKPROTECTOR should be selected by architectures with stack
canary implementation. It is not about the compiler support.
For the consistency with commit 050e9baa9dc9 ("Kbuild: rename
CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_' from the
config symbol.
I moved the 'select' lines to keep the alphabetical sorting.

A number of architecture ports are obsolete and getting dropped,
so we no longer want to track the respective features.
We already removed the lines for metag and mn10300, this does
the same edits for all the others.
For the remaining 21 architectures, this shows how many are known
to implement each given feature:
