This commit aims at improving speed by using better caching.
- Makefile, cache.mk: Split .cache.mk up
To allow caching of runtime path variables which are
project-specific, split .cache.mk up in .cache-project.mk and
.cache-projects.mk
- ldlibpath.mk: Cache ldlibpath, exepath and pythonpath
Place the output of $(call proj_query ldlibpath), $(call
proj_query, exepath) and $(call proj_query pythonpath) in
JW_PKG_LD_LIBRARY_PATH, JW_PKG_EXE_PATH, and JW_PKG_PYTHON_PATH
respectively, and cache the variables in make/.project-cache.mk.
- cache.mk: Use = instead of :=
Recursively expanded variables are nearly as fast as := variables
if the assigned value is a fixed string. And sometimes it's not,
rightly so, because variables get assigned below, as with
JW_PKG_XXX for instance.
- cache.mk: Use $(TOPDIR) as variable values
Replace absolute references to project's topdir by $(TOPDIR) with
sed. As soon as the project queries produce absolute paths, they
will be transformed into relative paths which allow the code base
to be moved to a different location and still remain functional
without a rebuild.

Remove unused code, and code which actually does something:
CACHED_VARS looks as if it's sufficently and more centrally defined
in make.mk, don't override that.

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.

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

dev-utils.mk is meant to provide targets like install-to-system,
which will be invoked during development
