Provide a fallback timercmp() definition (PR misc/59543)

timercmp() isn't a standard function (macro in this case)
so isn't guaranteed to exist on some random system that
we need to be able to build this on (since it is part of
the NetBSD tools setup).

So just provide a local copy of the definition, used in
the event that nothing else has already defined it.

re-turn off NLS and a couple of other things here (also used by tools build.)

add new generated files.

A simple '-DFC_NO_MT' in the Makefile works even better.

Do not remove UUID file when a scanned directory is empty.

pulled from the following upstream change:
https://gitlab.freedesktop.org/fontconfig/fontconfig/commit/5f12f564f8748deaa603adb7a4b8f616b6390ad4

It fixes that a cache file for an empty font directory is created
every time fc-cache is executed.

achVendID is an array not a pointer so it is always "true".
avoid clang warnings by not testing it.

Build fix. don't provide a conflicting declaration of FcObjectTypeHash and
FcObjectTypeLookup. they're defined in fcobjshash.h included just after.

oops, update these, not delete them. also add new fcstdint.h

Undo a local change now that our scandir() signature has been fixed.

Switch #pragma message(...) to #warning so it actually does anything.

Avoid __UNVOLATILE here, just inline the cast. We don't have
src/tools/compat's header here.
