jack_transport requires libreadline but not libncurses, so drop the latter.

Reportedly, f28523ff54 was incomplete.

CCFLAGS isn't honoured at all, the proper name is CFLAGS.

conf.write_config_header() defaults to remove=True, so conf.defines() is
empty afterwards. Consequently, config.h is empty, too.

Set remove to False, so calling it another time for 32_64 builds works.
