[PATCH] Makefile: add QUIET_GEN to "tags" and "TAGS" targets

From: Ævar Arnfjörð Bjarmason <avarab@gmail.com>
Date: Mar 28, 2021, 02:18 UTC
Message-ID: <patch-1.1-afd0c18ca86-20210328T021814Z-avarab@gmail.com>

Don't show the very verbose $(FIND_SOURCE_FILES) command on every "make TAGS" invocation. Let's also use the "cmd >x+ && mv x+ x" pattern here so we don't momentarily clobber the file.
