[PATCH 1/2] MAKEALL: allow users to increase verbosity and sidestep logging

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

MAKEALL always logs into a LOGDIR, but the output is not very talkative,
because for compiling, make is always called with -s (silent) option,
which prevents both V=0 and V=1 from affecting the output.

To make the output of MAKEALL more usefuly from CI, we want V=0 to have
an effect (i.e. print messages like `CC     version.o') and all output
to go to stdout/stderr, because it's more user friendly to have the
output directly in the Github Actions log instead of being in a zip file
that needs to be downloaded.

The former, we achieve by removing -s whenever V= is set and the latter
we achieve by allowing logging to be disabled by setting an empty string
as log directory.
