Some systems have an echo implementation which doesn't know how to
interpret a sequence of "\n". The word is that printf should be much
more portable, so let's try that instead.
# user how to enable verbose compiles.
ifeq ($(V),)
quiet_DOC := "Use \"$(MAKE) V=1\" to see the verbose compile lines.\n"
-quiet = @echo $(quiet_DOC)$(eval quiet_DOC:=)" $1 $@"; $($1)
+quiet = @printf $(quiet_DOC)$(eval quiet_DOC:=)" $1 $@\n"; $($1)
endif
# The user has explicitly enabled quiet compilation.
ifeq ($(V),0)
-quiet = @echo " $1 $@"; $($1)
+quiet = @printf " $1 $@\n"; $($1)
endif
# Otherwise, print the full command line.
quiet ?= $($1)
