[PATCH] configure: Suppress output from multi-do recipes

[Jonathan Wakely]

The FIXME comment saying "Leave out until this is tested a bit more" is
from 1997. I think it's been sufficiently tested.

ChangeLog:

	* config-ml.in (multi-do): Add @ to silence recipe. Remove FIXME
	comment.

OK for trunk?

This removes 44 lines of irrelevant noise from various build targets,
such as the 'check' target that runs the libstdc++ testsuite.
