The REG_PC define in disas/microblaze.c clashes with a define in
the Linux SPARC system headers:

/home/pm215/qemu/disas/microblaze.c:162:0: error: "REG_PC" redefined [-Werror]
 #define REG_PC  32 /* PC */

In file included from /usr/include/signal.h:326:0,
                 from /home/pm215/qemu/include/qemu/osdep.h:86,
                 from /home/pm215/qemu/disas/microblaze.c:36:
/usr/include/sparc64-linux-gnu/sys/ucontext.h:96:0: note: this is the location of the previous definition
 #define REG_PC  (1)

Since the code doesn't actually use the REG_PC define
anywhere, the simplest fix is just to remove it.
