# 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.

# [h]act II: the plot thickens
#
#     * Specifying two targets that each configure libuv works
#       when the rules are executed sequentially,
#     * but when attempting a parallel build, it is likely Make
#       will try to configure libuv simultaneously.
#     * We can specify a dependency between the two targets so
#       that execution of their rule(s) is serialized.
#     * Further, libuv does not seem to be friendly towards
#       parallel builds either. A true fix is out of scope here
#     * ...so we must instruct Make to only use one job when it
#       attempts to build libuv.
