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.
