Upstream-Status: Backport [From https://github.com/linux-test-project/ltp/commit/40a2457cb8ec42a05a2f96b0810057efdb2a55f5]

gcc 5.x defaults to -std=gnu11 instead of -std=gnu89 which causes
semantics for inline functions changes.

The standalone 'inline' causes error with gcc 5 such as:

git/testcases/kernel/syscalls/kill/kill10.c:355: undefined reference to `k_sigaction'

Replace inline with static inline to be compatible with both gcc 4 and 5.
