Without this, the NDK stub libm.so files think we've had the new O
functions since the beginning of time.

FreeBSD doesn't seem interested in having low-quality implementations of
these functions:
cacoshl, cacosl, casinhl, casinl, catanhl, catanl, ccoshl, ccosl, cexpl,
clog, clogf, clogl, cpow, cpowf, cpowl, csinhl, csinl, ctanhl, ctanl.
And they still haven't got round to writing good implementations, so for
now let's just take the NetBSD ones so we have the full set.
