I don't really care about the err.h functions; these are legacy junk
and should not be used in modern programs. I'm pretty much indifferent
to whether they get _Noreturn, but if so, let's save it for a separate
patch/commit.
As for a_crash, I'd like having it there in principle, but I don't
like duplicating the #if logic in each platform's atomic.h. Since this
code is internal and already depends on __asm__, it probably would not
hurt to just use __attribute__((__noreturn__)), perhaps with #ifdef
__GNUC__ around it. It's the public headers that need to be compatible
with an arbitrary C99/C11 compiler; the internals of musl depend on
"minimal GNU C" in the form of inline asm and some related things.
This can also be a separate patch/commit since it's unrelated to
making the headers conform to C11.
