[Buildroot] [PATCH 2/2] package/busybox: redirect errors to /dev/null

[Vincent Fazio]

When busybox.mk gets read, pkg-conf gets executed to determine the
location of relevant libraries.

When Busybox is built with per-package directories enabled, a number of
errors related to executing pkg-conf occur because directories have not
been synced to provide pkg-confg at the point when it executes.

These errors occur in stages prior configuring the package and are of
little consequence so redirect the errors to /dev/null.
