This adds another mode to do_gcc_core_backend that builds libstdc++
against an alternate libc implementation.

Use LIBC_PICOLIBC_CXA_ATEXIT to keep this name in the same 'namespace'
as the other picolibc config names.
Enable retargetable locking by default. This allows the few locks in
picolibc to be implemented by the execution environment, rather than
disabling the locking code.

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.

Currently when building cross-canadian toolchain for macOS
the folowing error happens when GCC is configured:
|ld: illegal text-relocation to '___gmp_binvert_limb_table' in
|... /.build/... /buildtools/complibs-host/lib/libgmp.a(mp_minv_tab.o) from '___gmpn_divexact_1' in
|... /.build/... /buildtools/complibs-host/lib/libgmp.a(dive_1.o)
|collect2: error: ld returned 1 exit status
Apparently this might be solved with GMP configured with "--with-pic",
even though we're talking about static library here.
That solution was found here:

Even though GCC as a compiler has nothing to do with a C library
being used it still makes sense to know about Newlib's compact
implementation of IO functions:
* For targets like MSP430 which require to have such a tuned
Newlib if "-mtiny-printf" is passed to the GCC's command-line [1]
* For correct compilation of the following GCC's own DejaGnu tests [2]:
- gcc/testsuite/gcc.c-torture/execute/920501-8.c
- gcc/testsuite/gcc.c-torture/execute/930513-1.c
- gcc/testsuite/gcc.dg/torture/builtin-sprintf.c
- gcc/testsuite/gcc.c-torture/execute/ieee/920810-1.x

So we add that missing cross-dependency now.

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

* Do not assume a release has a tarball if src_release is set to "n".
* Do not assume versions in repositories are all experimental.
* Allow versions to define their default repository_branch,
repository_cset, repository_subdir and bootstrap.
* Do not expect mirrors, archive_filename, archive_dirname,
archive_formats and signature_format from a version if src_release
is set to "n".
* Add version_number to allow version names to be different than the
version number. When given, use version_number to compare against
the milestones.

Add building on MacOS X as part of the CI testing.
A few notes:
* We exclude mips64-unknown-linux-gnu as the linux kernel headers need
<byteswap.h> that is a GNU extension to build elf-entry.c and does
not exist on Mac OS X.
* We create a SPARSE image filesystem to ensure we have are doing the
builds in a case sensitive fs.
