[Qemu-devel] [PATCH] checkpatch.pl: disable arch-specific test for syscall tests

[riku . voipio]

From: Riku Voipio <address@hidden>

Linux-user and bsd-user code need ifdef guards for new system
calls that aren't implemented on all host/target combinations.
Allow ifdefs for system calls when defined as __NR_foo.
