It's the parallel make, so multiple .lo targets can be built at once.  If the make starts two in parallel they will both attempt to create 'objs' and one must fail.  That's why:

	mkdir objs 2>/dev/null || test -d objs

is safer; because it reliably succeeds if objs exists *or* is created.  It's quiet and doesn't require the '-' (ignore errors) though you may still want the '@'.
