minix/tools/Makefile.gnuhost
Antoine Leca 866355d930 GNU tools: improvements to fetching process
- Do not run the fetch.sh script every time
- Do not run the configure script with MKUPDATE=yes (build.sh -u)
- The fetched GNU source are hidden from `git status`
- With CLEANFETCHED=yes, `nbmake -C tools cleandir` will remove the
fetched GNU source and return the MINIX tree to its pristine state.
- Avoid (harmless) message when building in parallel, about find
running against an inexistant path

Notice that the GNU tools are "installed" on every run, even with
MKUPDATE=yes; this is a feature of the NetBSD build system, because
in case of changes in dependencies it is impossible to know them.
See commit 1.27 2004-06-12 of tools/Makefile.gnuhost in NetBSD's src/

The downloaded tarballs are not removed with CLEANFETCHED:
they are supposed to be unmodified, and the exact name is not known
to the Makefile's, since it is engraved in each fetch.sh script (and
we do not want to have the same information in several places.)

# 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.
