This add a spurious space to the QUIET variable. Not really important, but we
normally avoid that.
Also, maybe an easier solution is:
# Search for s only in the short options
QUIET := $(if $(findstring s,$(firstword $(MAKEFLAGS))),-q)
(Note that GNU make converts something like --silent into an s in MAKEFLAGS, and
that all the short options are collected to the beginning of MAKEFLAGS.)
