# This is a silly hack necessitated by the fact that libuv uses configure
#   
#    * Making 'all' obviously requires outside/libuv, 
#      which requires the libuv Makefile to be created.
#    * Making distclean on outside/libuv destroys the makefile.
#    * ...so configuring outside/libuv is parodoxically required 
#      in order to distclean it!
#    * But what if developer types 'make distclean all' ?
#    * first target makes libuv Makefile, then destroys it...and 
#      second target knows that it was made.
#    * ...so second target borks.
#    * Solution: make libuv not only depend on its own Makefile, 
#      but on a side effect of creating its own makefile.
