The 3.3 kernel headers define the umode_t type within a __KERNEL__
preprocessor ifdef region. This results in a broken kernel header in the
buildroot toolchain.

Committed, thanks. It seems socat/syslinux should get updated to not
include this header, but as there's no upstream releases fixing this it
makes sense to add it for now.

+Fix a problem with the 3.3 kernel headers. Specifically, the umode_t type
+is defined within a __KERNEL__ preprocessor ifdef region, and so the type
+is not usable by non-kernel code. Visit the following URL for more details.
