Subject: [PATCH] remove bogus nan.h header

In theory somehow maybe possibly sort of, glibc has bits/nan.h, and in
gentoo-historical-2.git:

    add rogue/xatrix game support #33029

a patch was added to switch it to including that header instead.
Helpfully, bits/nan.h has this to say:

#ifndef _MATH_H
#error "Never use <bits/nan.h> directly; include <math.h> instead."
#endif

... or at least it does, on versions of glibc that installed such a
header. In 2.27 the header file was removed entirely.

Now, "fortunately", g_local.h had already included math.h, which meant
the best efforts of glibc developers to demonstrate this is an error
were evaded; no error was emitted. Unfortunately, glibc 2.27 is long in
the past and this code no longer builds, times 2 because now we patched
it to be extra silly.

Fix it properly this time.
