This commit makes it possible to successfully run "make all" against ytools'
again, with TARGET_TUPLE set to i686-ms-w64-mingw. Lots of minor and major
tweaks here and there.
The biggest diff is a move of the architecture-related definitions into
platform.mk. The are needed pretty early on, so that seems reasonable.
Making this work again is part of the larger effort to support cross
buildchains in a more concise way, i.e. without so many if ($(TARGET),mingw))
all over the place. TARGET's relevance should dwindle, until it's finally taken
over by the TARGET_XXX variables extracted from TARGET_TUPLE or TARGET_TRIPLET.

C++ definitions are numerous, and they shouldn't pollute variable space and
performance outside of directories containing C++ files. This commit pushes
them into a defs-cpp.mk file.
