PROC_PC() macro usage in kern/kern_clock.c

["Toru Nishimura" <locore64%alkyltechnology.com@localhost>]

Guys,

There are two ports, sh3 and mips, which define PROC_PC() macro in
cpu.h.  They look both wrong and un-compileable indeed.  It's apparent
they are a sort of leftovers never used so far.  Is it ok to remove the
#define from cpu.h and the usage in kern/kern_clock.c?
