If this fails try out if mfspr268 works.

Use OPENSSL_ppccap=0x20 for enabling mftb,
OPENSSL_ppccap=0x40 for enabling mfspr268,
and OPENSSL_ppccap=0 for enabling neither.

crypto/armcap.c, crypto/ppccap.c: stricter use of getauxval()

Having a weak getauxval() and only depending on GNU C without looking
at the library we build against meant that it got picked up where not

exists from that version, there's no real need to make it weak.
