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 Signed-off-by: Jan Lindemann <jan@janware.com>
