Ok, provided this doesn't break NetBSD a.out pic code (which has limited 
relocs).

Incidentally, for the example you cite, the optimal PIC code would be:

f:
	ldr	r0, .L3
.L2
	ldr	r0, [pc, r0]
	mov	pc, lr
.L3
	.word a-(.L2+8)

There's no need to indirect off the GOT for this example at all!  However, 
in the more general case it probably gives better sub-expression 
elimination to do so.
