[LTP] [PATCH] replace inline with static inline for gcc 5.x

[kai.kang@windriver.com]

From: Kai Kang <kai.kang@windriver.com>

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

GNU89 inline: Same as C99 extern inline.

So the standalone 'inline' causes error such as:

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

Replace inline with static inline to fix this issue.
