21.1Stv#
31.1Stv# Rules used when building a GNU host package.  Expects MODULE to be set.
41.1Stv#
51.1Stv# There's not a lot we can do to build reliably in the face of many
61.1Stv# available configuration options.  To be as low-overhead as possible,
71.1Stv# we follow the following scheme:
81.1Stv#
91.1Stv# * Configuration is only re-run when an autoconf source file (such as
101.1Stv#   "configure" or "config.sub") is changed.
111.1Stv#
121.1Stv# * "config.status" is run to rebuild Makefiles and .h files if an
131.1Stv#   autoconf-parsed file (such as Makefile.in) is changed.
141.1Stv#
151.1Stv# * If UPDATE is set, "make install" is only run if a build has happened
161.1Stv#   since the last install in the current directory.
