time(2) missing for target i386-elf

[ramsdell at mitre dot org (John D. Ramsdell)]

I used the latest newlib along with binutils and gcc to build a
cross-compiler with a target i386-elf.  This compiler was used Lua
<http://www.lua.org>, with the aim of placing it inside an operating
with consists only of a small kernel and a Lua interpreter.  When I
linked Lua with libm, libc, and libnosys, there was still one
undefined symbol, time.  The Lua authors claim time(2) is part of ANSI
C, however my GNU/Linux manual page says it conforms to SVr4, SVID,
POSIX, X/OPEN, BSD 4.3.  In any event, is there a reason time(2) is
not part of the newlib C library?  If the reason is simply no one has
submitted a patch that adds this functionality, I'll gladly supply the
code.
