[PATCH] Fix MIPS n32/n64 compile error in syscall.c

[David D. <dd...@ca...>]

syscall.c will not build under mips-n32 or mips-n64.

In syscall_enter() there is a call to ptrace() with an undefined 
variable 'pid'.  This should be replaced with 'tcp->pid'.  Attached is a 
patch that fixes the issue for me.

Please apply if approved.

Thanks,

	* syscall.c (syscall_enter): Pass tcp->pid to ptrace
	in MIPS-n32/MIPS-n64 case.
