# These test scripts use little cpu but contain sleeps etc.  So when
# there are several, we are going to want to run *loads* in parallel.
#
# Ideally we would do something like "every one of these counts for a
# tenth of a job" but make can't do that.  So bodge it: we treat all the
# tests as a single job, and disconnect the parent's jobserver.
#
# make.info says $(MAKE) causes special handling of the rule but only
# if it's written literally like that in the rule, hence this
# indirection.  We need no squash MAKEFLAGS and MFLAGS too.
# MAKELEVEL seems like it will be fine to pass on.
