1. Allows picolibc's stdio to be used with c++ applications
2. Includes arm exception information in link rules
3. Adds picolibc include directory to c++ header paths.
These patches are all upstream in picolibc and included in version
1.5.

ftp://invisible-island.net/ncurses doesn't actually have the numbered
ncurses tarball. We've not noticed because we fall back to using the GNU
mirror which does. It's also ftp which is being deprecated.
Switch to https://invisible-mirror.net/archives/ncurses which has the
actual tarballs and provides a secure connection.

If we are targetting an aarch64-none-elf toolchain we end up running

fixed in upstream gcc so just backport the patch to gcc-10.2.0

When building aarch64-unknown-linux-gnu on MacOS X, aarch64-builtins.c
files doesn't build by default with clang on MacOS X. We need to pass
-std=gnu++11 when building the file for things to work with clang.

included in there, these are pulled out of the binutils-2_35-branch post

Backport change from glibc upstream that defines RELEASE as stable
instead of release. This will at least cause the default_cflags to be
set to expected default values again.
Ref issue #1396, although the bigger issue of respecting crosstool-ng
CT_GLIBC_EXTRA_CFLAGS is most likely still not fixed.

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

Two patches from 0.18.8.1 were dropped:
- one changing the declaration of environ is no longer needed, the
corresponding files no longer have this declaration
- one with Woe32 fixes for -O0 may need to be re-added but only after I
find what configuration breaks without it; gettext sources overwent a
massive restructuring so this patch should not be applied without
testing.
