The command "make -j8 C=1 CHECK=scripts/coccicheck" produces lots of
"coccicheck failed" error messages.
I do not know the coccinelle internals, but I guess --jobs does not
work well if spatch is invoked from Make running in parallel.
Disable --jobs in this case.

Changes in v2:
- Grep '-j' instead of '--jobserver-auth'.
'--jobserver-*' is not a stable option flag.
Make 4.2 change '--jobserver-fds' into '--jobserver-auth'
- Add -q option to grep
