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

#

# There's not a lot we can do to build reliably in the face of many

# available configuration options. To be as low-overhead as possible,

# we follow the following scheme:

#

# * Configuration is only re-run when an autoconf source file (such as

# "configure" or "config.sub") is changed.

#

# * "config.status" is run to rebuild Makefiles and .h files if an

# autoconf-parsed file (such as Makefile.in) is changed.

#

# * If MKUPDATE != "no", "make install" is only run if a build has happened

# since the last install in the current directory.
