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.

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

We need this to have different polarity for different platforms (Windows
vs RedHat). I don't know how to autodetect this for now, so I'm just
doing it manually.
Soft-float calling convention is default, but an alternate hard-float
calling convention (with doubles passed as in soft-float, but floats
passed as in hard-float) is supported.
Augment the handling of --with-arch such that it can properly set XLEN,
atomics flags, and floating point flags. The original
--enable-atomics/float flags are still respected, but if --with-arch is
provided then it supersedes other options.
It's no longer the case that building the toolchain with
"--disable-float" turns off floating-point by default. This passes the
correct arguments to all the various sub-configures in order to ask for
floating-point support to be either enabled or disabled.
I commited this too quickly last time and it's been breaking a whole
bunch of stuff. Until I managed to get multilib working in a sane
way, I'm just going to go ahead and turn it off by default. You can
still pass "--with-arch", but doing so while also passing things like
"--enable-multilib" or "--disable-atomics" might have unexpected
results.
I have no idea why, but the installed "sed" wrapper never terminates
on RHEL. If I don't use the wrappen the the tools build fine, so this
just uses the already set autoconf variables to attempt to determine
if the system sed/awk are gsed/gawk and if they are then this avoids
using the wrappers.
There's a few oddities here:
* I have no idea why the sed wrapper fails, as it seems super safe.
* I haven't run into any awk problems, but I figured I'd treat it the
same as it isn't any harder.
* We shouldn't have to support 10 year old distributions.
Hopefully this doesn't break anyone's builds...
