      3 # Rules used when building a GNU host package.  Expects MODULE to be set.

      5 # There's not a lot we can do to build reliably in the face of many
      6 # available configuration options.  To be as low-overhead as possible,
      7 # we follow the following scheme:
      8 #
      9 # * Configuration is only re-run when an autoconf source file (such as
     10 #   "configure" or "config.sub") is changed.
     11 #
     12 # * "config.status" is run to rebuild Makefiles and .h files if an
     13 #   autoconf-parsed file (such as Makefile.in) is changed.
     14 #
     15 # * If UPDATE is set, "make install" is only run if a build has happened
     16 #   since the last install in the current directory.
