Yes...maybe we have too many flavours; the idea is (where to document
this, HACKING maybe)

   libc-mini: the very minimal to bootstrap a new ARCH (exit, write, strlen)
   libmes:    (why not libc-mes?) what's needed for Mes.c/mescc
   libc:      a "reasonable" c library; very arbitrary definition
              not sure exactly what it's purpose is
              used in the 5x-* 6x-* tests, anyway...
   libc+tcc:  minimal c library for tcc
   libc+gnu:  minimal c library for the current guix bootstrap

So, "libmes" needs to be either in the binary seed, or it would need to
be bootstrapped - libc and beyond are only needed in source form.  The
name is weird, libc-mes would be better, no?

Now that we have M2-Planet, we may not need to be just as careful as
when I feared we'd need to code and maintain those in assembly, but
still.

HTH,
Janneke
