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:
9 # * Configuration is only re-run when an autoconf source file (such as
10 # "configure" or "config.sub") is changed.
12 # * "config.status" is run to rebuild Makefiles and .h files if an
13 # autoconf-parsed file (such as Makefile.in) is changed.
15 # * If MKUPDATE != "no", "make install" is only run if a build has happened
16 # since the last install in the current directory.
20 # Disable use of pre-compiled headers on Darwin.
