# 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.
