[PATCH] i386 syscall tracing of bogus system calls

In 2.4, strace will show you all bogus system calls a process tries.  In
2.6, it only shows you stubs < __NR_syscalls, and there is no tracing stop
for large bogus system call numbers.  I can't see why this was changed, so
I am assuming it was accidental.

This patch restores the expected behavior that syscall tracing shows every
bogus syscall attempt.
