[patch] contrib/config-list.mk: Allow to build all targets individually

[Jan-Benedict Glaw <jbglaw at lug-owl dot de>]

Hi!

For my Build Robot, I'd like to change contrib/config-list.mk to be
more generally useable. This patch allows to override the defaults for
$(host_options), which currently mentions mpc's location.

  The second change allows to print the list of buildable targets,
which saves me the need to to a crude parsing of this make file.

  Finally, the patch changes the list of targets so that they don't
contain the "=" character any more. You can use this make file to
build individual targets like this:

	make -f ../gcc/contrib/config-list.mk log/<targetname>-make.out

However, this does not work for target names with "=" in them (ie.
arc-elf32OPT-with-cpu=arc600), because the output log filename would
be parsed as a variable assignment.



2013-11-24  Jan-Benedict Glaw  <jbglaw@lug-owl.de>

	* config-list.mk (host_options): Allow to override it.
	(LIST): Change "=" to "EQUAL".
	(list): New target listing all configurations.
	($(LIST)): Substitute "EQUAL" back to "=".
