Wow! Thank you for all the work on this.
Patches slightly modified (indentation, wording on commit messages) and
pushed!

Hello Guixers,
This adds avr as a platform to GNU Guix allowing to cross-compile
packages to it.
For the impatient, with this patch series one can build the provided
unity package with this invocation:
./pre-inst-env guix build unity --target=avr
It uses the AVR Libc as the default libc and fully builds a
cross-compiler using the AVR Libc instead of building them separately
like it's done currently. This could allow to use other of front-ends of
GCC in the future if possible, however, Fortran and Objective-C
front-ends don't build right now for AVR, haven't tested any other
front-ends.
This also adds the cross-toolchain module for instantiating
cross-toolchain packages, this is to avoid each platform defining a
module like avr to instantiate a toolchain, this helps in avoiding
circular dependencies as cross-toolchain should depend only on
cross-base and that'd be it.
I think could've added cross-toolchains there for MinGW though, but I
don't have a need for it but allows others to do so. Perhaps it could
be a requirement that to add a platform one needs to add a
cross-toolchain package.
I enabled multilib support for AVR as most embedded platforms will need
it, which makes me think, perhaps should the platform record contain a
`mutlilib?' field?
Information about individual patches:
On [PATCH 05/23] I didn't find a better way of deleting the
--disable-multilib flag from GCC configure flags, if anyone has a better
idea let me know.
The [PATCH 01/23] and [PATCH 02/23] are optional but there
might be some platforms defined in the future that don't have
a proper libc and it still should be fine to use these I think.
The [PATCH 21/23] fixes a bug in the meson-configuration module
and can be applied independently.
Feel free to cherry pick the interesting/trivial patches.
PS:
I CC'ed the embedded team and Maxim Cournoyer as I saw his current work
on QMK firmwares and could be of interest to him.
