The Xtensa gcc does not seem to like output on /dev/null. The applied patch
on dhcpcd is thus unusable, and a more verbose version involving a temporary
file is needed.

-Upstream status: another implementation was submitted, modified by
-maintainer Roy, then simplified based on my suggestion. This patch is a fold
-of the two upstream patches:
+Upstream status: backport of
http://roy.marples.name/projects/dhcpcd/info/5f4bf91142fceac502c478886aeb5079a184bb43
-http://roy.marples.name/projects/dhcpcd/info/26bc10be2405659bdf31d690a72d377d6b67ebd4
+
+Note: a simplification of this patch was accepted upstream, but turns out to be
+non-usable by the Xtensa architecture. This was also reported upstream and
+should normally be reverted soon.
