I'm trying to clean up some of my test scripts, and one issue is that
I've got two QEMU builds: one for user-mode emulation and one for
system-mode emulation. This adds an autoconf flag that allows me to
avoid the duplication.

This lets users select whether or not to build libsanitizer, which
currently does not support rv32 and thus can't be enabled by default.

The upstream musl libc does not support 32bit RISC-V builds.
We therefore only allow building the 64bit version (i.e.,
riscv64-unknown-linux-musl-).

Since musl is already incorporated into the build system (see for
example configure.ac, Makefile.in), this patch adds a submodule for
musl based on the current v1.2.2 release.
The GitHub Actions configurations have also been updated to include
the musl based toolchain.

Both the glibc and newlib submodules are already pointing to the
upstream repositories where development happens.
Since they are therefore not referring to RISC-V specific forks,
this patch unifies the directory naming by only prepending the
"riscv-" prefix to submodules that point to repositories in the
riscv-collab Github organization.

The recent addition of an override for the QEMU source directory left
the default pointing to the wrong submodule.

This patch introduces a configure-time source-dir override for QEMU
similar to the existing overrides for the other toolchain sources.

We set CXX=riscv64-unknown-linux-gnu-g++ (or something like that) when
building glibc, but don't actually build a C++ compiler during stage 1.
Under normal conditions this shouldn't cause any issues: that's either a
working compiler (from PATH) or doesn't exist, in which case glibc's
build scripts do the right thing and turn off C++. Unfortunately I'm in
the pathological situation of having a slightly-incompatible g++ in
PATH, which glibc then attempts to use only to throw an error when
linking (glibc isn't testing that much of the C++ toolchain, see
<https://sourceware.org/bugzilla/show_bug.cgi?id=24183>).
This simply sets CXX to something that's unlikely to exist during the
glibc build, so the build scripts don't get confused. I tried setting
this to false, but everything was italic.

This helps identify the exact sources used for building the compiler.

| After : gcc version 11.1.0 (g480822473a4a)

The variable MULTLIB_NAMES does not exist but is used when
generating the dependencies for the target build-libc for glibc.
Even when adding the missing 'I' (for MULTILIB_NAMES) there is
still no variable with this name.
So the whole dependency generation is useless, becauese it was not
needed so far. Looking into detail why it is so, we can find the
answer in the dependency list of the target 'stamps/build-gcc-linux-stage2'.
Let's fix this by setting the dependencies for build-libc right.
The dependencies for 'stamps/build-gcc-linux-stage2' stay as they are
not wrong.

- PR 94853 and PR 86153 are reoslved
- gfortran.dg/elemental_subroutine_3.f90 seems pass now.
- g++.dg/tls/thread_local4* added to allow list since they might random
fail on qemu, and hard to reproduce.
