Split the process to fetch GNU tools (until now embedded within tools/Makefile.gnuhost) into a new Makefile.fetchgnu, MINIX-specific hence relocated, which is to be also used to fetch sources even when not building the tools. Use it for binutils too. Improve documentation. Also do not run configure on each run when MKUPDATE=yes The .WAIT serialization instruction between fetching and other configure sources was raising a new run of configure at each compilation. Avoid it by using two rules. Change-Id: Ie24950ccbb5c5067f3c1ea57b7bd8294e4c9445e

# 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.
