Makefile.gmakehost revision 1.5

      3 # Rules used when building a GNU host package.  Expects MODULE to be set.
      4 # This version runs ${TOOL_GMAKE} instead of ${MAKE}
      5 #
      6 # There's not a lot we can do to build reliably in the face of many
      7 # available configuration options.  To be as low-overhead as possible,
      8 # we follow the following scheme:
      9 #
     10 # * Configuration is only re-run when an autoconf source file (such as
     11 #   "configure" or "config.sub") is changed.
     12 #
     13 # * "config.status" is run to rebuild Makefiles and .h files if an
     14 #   autoconf-parsed file (such as Makefile.in) is changed.
     15 #
     16 # * If MKUPDATE != "no", "make install" is only run if a build has happened
     17 #   since the last install in the current directory.
