Re: ofwboot.xcf and gcc 4.8 and ppc 601

Still have same issue after your fix.  I sent my ofwboot.xcf to your
email.

Also, it may not matter, but I think
src/sys/arch/macppc/stand/ofwboot/Locore.c may need to have %r0=0
before bats are initialized, or use %r9 instead of %r0 at processor
check:

"       mfspr   %r9,287      	\n" /* mfpvbr %r9 PVR = 287 */
"       srwi    %r9,%r9,0x10   	\n"
"       cmpi    0,1,%r9,0x02  	\n" /* 601 CPU = 0x0001 */
"       blt     1f		\n" /* skip over non-601 BAT setup */
