# $NetBSD: Makefile.gnuhost,v 1.44.8.3 2018/10/26 15:12:53 martin Exp $ # # 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. .include # Disable use of pre-compiled headers on Darwin.
