[Just correcting the -r's to be -r321706.]

I experiment with system clang targeting powerpc
(and powerpc64). Until recently I could buildkernel
via system clang 4 (but it had problems if tried to
boot such a kernel). After clang 5 it no longer
completes the buildkernel. I'm submitting based on
a -r321706 build attempt. The system binutils are
in use.
The technical material from the submittal is. . .
First I list what the R_PPC_PLTREL24 is tied to
then the error text then the build context.
objdump reports that the .text+0x2b94 involved
is in aha_isa_probe and is a reference to aha_alloc:
