Aside from stdnoreturn.h, noreturn stuff is done.
uchar.h and time.h have some nontrivial functions we need to add, I

It's impossible for musl to set these; that's up to the compiler, and
it would have to be done in the gcc specfile or builtin gcc specs.

Of course we can just publish that the command to invoke the C11
compiler is:

gcc -std=c11 -D__STDC_NO_ATOMICS__ -D__STDC_NO_THREADS__

However, I'd actually like to get atomics supported soon, at least on
GNUC compilers that have the right __builtin or __sync builtins. (Or
adapting atomic.h to be a public header, but I think the stuff in
stdatomic.h has to be somewhat type-generic, which makes it hard...)
