These variables denote the flags used in compiler and linker rules.
They are defined as REAL_(CPP|C|LD)FLAGS ?= BUILD_(CPP|C|LD)FLAGS
and provide a means to override the flags assembled cumulatively.

USE_DISABLE_COMPILER_OPTIMISATION_OPTS = true disables options targeted
at disabling optimization features, which were introduced to facilitate
debugging in the first place, but make the commandline harder to compare
to others while troubleshooting the compile process

Code generated for Cortex M3 stopped working after adding -L$(TC_SYS_ROOT)/lib.
The problem is that libc et al have to be taken from $(TC_SYS_ROOT)/lib/thumb,
which is correctly taken if explicit -L is left out.
Probably breaks mingw, to be tested and fixed in the next iteration.

Add support for building the firmware of the Cortex M3 ST-NUCLEO-F103RB
development board with an STM32 microcontroller. This commit add some hooks,
notably support for tagged templates, but adds lots of crap, too, notably
makefiles and variables that should have different names and / or
functionality.
New makefiles are: Mcu-defs.mk mcu-exe.mk mcu-flash.mk mcu-tags.mk
mcu-topdir.mk tagged-tmpl.mk, a new directory is tmpl/tagged.

This commit takes the MinGW cross compilation further into the direction of
being a more general framework for cross compilation. Changed some variable
names that are too specialized, notably MinGW tool chain directories,
compilers, utilities.

platform.mk is sometimes included before defs.mk, e.g. from
$(TOPDIR)/make/proj.mk, then these definitions are necessary

The clean target now doesn't remove meta files which enforce a new pull if
absent. distclean is the new clean.

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.

Reordered some variables in defs.mk and defs-cpp.mk for clarity. Most notably
FULL_NAME was moved back into defs.mk, which amounts to a bugfix.

This commit tries to remove the necessity to call projects.py from $(TOPDIR) to
speed up recursive builds over all projects yet again. This is a major
undertaking. There are two variables which are filled py projects.py in
$(TOPDIR): PREREQ and PREREQ_DIRS. Sadly, the latter is a path relative to
$(TOPDIR)/make, so this is kind of pointless. Unless the cache is maintained in
$(TOPDIR), a thing I tried to avoid. So this commit is only able to cache
$(PREREQ), not $(PREREQ_DIRS), which still is a hassle. Introduced defs-dirs.mk
for that, to make it accessible to make.mk, and modified all the other parts of
the machinery, too.

This commit sees several improvements to the build performance:
- Introduce cache.mk, which creates makefiles caching often used
variables, per tree and per project.
- Define more variables with := enclosed in condistions, instead of
defining them with ?=, because the RHS of ?= is expanded deferredly.
- Add more definitions for executables.
- Move some more specialized definitions out into specialized makefiles,
notably htdocs.mk and tmpl.mk

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.
