make sources directory customizable and dynamically created this allows sharing a sources directory between multiple checkouts or independent toolchain-using projects. also, during distclean, only remove the in-tree sources directory, not a custom/external one. this is a safety measure in case the SOURCES variable is set to something stupid like blank, root directory, or some large shared directory.

avoid installing stage0 gcc previously the stage0 gcc was installed to the output location during the build, then replaced later by the final gcc. this violates the principles of make and simply wastes time. the stage0 gcc is usable in-place without installing it, so we can simply do that instead.

replace steps directory with stamp files in source/build dirs this makes it easy to rebuild components simply by removing the source or build directory with rm -rf; no separate action on the steps files is needed. some dependencies are also changed to order-only so that update/rebuild of one component does not force unnecessary rebuild of another. new convenience pseudo-targets are also added.
