Since single_step_syscall.c depends on sys/syscall.h and
its include, asm/unistd.h, we should check the availability
of those headers.
Without this fix, if gcc-multilib is not installed but
libc6-dev-i386 is installed, kselftest tries to build 32bit
binary and failed with following error message.
In file included from single_step_syscall.c:18:
/usr/include/sys/syscall.h:24:10: fatal error: asm/unistd.h: No such file or directory
#include <asm/unistd.h>
^~~~~~~~~~~~~~
compilation terminated.
