this is merely documenting what glibc has historically done, and glibc
has historically tried to copy BSD in this area.  even then, the manpage
probably should be adjusted to document sysmacros.h directly since that
is where glibc has always placed things.

i really have no idea how toybox code is structured.  feel free to add
the include to wherever you feel is appropriate.

feel free to read the thread:

glibc is the process of deprecating, and musl/uClibc would follow suit,
if not just drop the include altogether.
