configure: use make --quiet

Under some circumstances, make will print "helpful" extra messages to stdout
instead of stderr:

make[1]: Entering directory /usr/local/google/builder/master/vendor/mindspeed/drivers'
fci/lib cmm
make[1]: Leaving directory /usr/local/google/builder/master/vendor/mindspeed/drivers'

I don't know why this doesn't seem to happen in regular builds, but it was
upsetting the autobuilder.  Add --quiet to prevent these messages when
running make in a context where we want to parse its output.
