[OE-core] [PATCH 2/9] icecc: Remove output on stderr when calling which

[Tobias Henkel]

From: Tobias Henkel <tobias.henkel at bmw-carit.de>

The icecc class often uses 'which' for determining paths. This leads
to many messages on stderr in case 'which' doesn't find the
executable. Redirecting stderr to /dev/null inhibits these messages as
the result is handled correctly anyway.
