Subject: [PATCH] pkg-kernel-module: die if kernel module support is disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Test the configuration of the kernel to see if loadable module support
is enabled, and error out otherwise. This makes build failures of
external kernel modules less confusing.

[Thomas: tweak the commit log.]
