3# Rules used when building a GNU host package.  Expects MODULE to be set.
4#
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.
