[Buildroot] [git commit] pkg-kernel-module: die if kernel module support is disabled

commit: http://git.buildroot.net/buildroot/commit/?id=8df95d926e963601c727defeb4ab90ce2368da70
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.]
