Dear gnustep developers,
Here are some trivial build tweaks for mingw64.
As ifeq/ifneq of GNUmakefile do not support condition clause such as AND/OR,
tweaks were just copy&paste of mingw32 section.
If other solution is possible,it would be applied.
Mingw64 build barely manage to compile at current status due to the lack of msys2/mingw.
However, it might be able to used till msvc(and winobjc) replace mingw.
The affected libs are make, base, gorm, projectcenter, systempreferences, ucsdata and xcode.
(the patch for make contains latest config.guess and guess.sub from savannah,
and that for xcode substitute deprecated bzero() to memset() additionally.
Sincerely yours,
Lee, Seong-Gu
