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.
