kernel: cherry pick patch removing __linux__ check

Browse Source 
This is already included in newer upstream. Needed to build BPF programs
using the MIPS kernel include files.

Without this patch, clang fails with "#error Use a Linux compiler or
give up." in sgidefs.h when building BPF programs.

Subject: MIPS: Remove superfluous check for __linux__
When building BPF code using "clang -target bpf -c", clang does not
define __linux__.
To build BPF IR decoders the include linux/lirc.h is needed which
includes linux/types.h. Currently this workaround is needed:
https://git.linuxtv.org/v4l-utils.git/commit/?id=dd3ff81f58c4e1e6f33765dc61ad33c48ae6bb07
This check might otherwise be useful to stop users from using a non-linux
compiler, but if you're doing that you are going to have a lot more
trouble anyway.
