make/[Makefile|*.mk): Improve variable caching 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.
