Build failure of kernel v4.14-rc due to error in tools/perf

Build failure of kernel v4.14-rc due to error in tools/perf

[Akemi Yagi]

Hi,

The build of kernel v4.14-rc1 for i686 fails on RHEL 6 with the error 
in tools/perf:

util/syscalltbl.c:157: error: expected ';', ',' or ')' before '__maybe_unused'
mv: cannot stat `util/.syscalltbl.o.tmp': No such file or directory

This is fixed by placing/moving

#include <linux/compiler.h>

outside of #ifdef HAVE_SYSCALL_TABLE as shown in the patch below.

Thanks,
