[klibc] ppc64: build with -mcmodel=small
If available, use -mcmodel=small. klibc is small enough that we
should never hit the limits of the small memory model.
This produces better code, for example:
000000000f003890 <.strcasecmp>:
f003890: 3c a2 ff fe addis r5,r2,-2
...
f003898: 38 c5 23 58 addi r6,r5,9048
...
f0038ac: 7d 46 50 ae lbzx r10,r6,r10
vs:
000000000f0037c4 <.strcasecmp>:
f0037c4: e8 c2 81 48 ld r6,-32440(r2)
f0037dc: 7d 46 50 ae lbzx r10,r6,r10
