vax libm is missing various symbols including llround and rintf.

I mechanically compared amd64 libm and vax libm.  The following symbols are in amd64 libm but not in vax libm (possibly missing, or possibly not applicable to vax -- I didn't put any further thought into this):

acoshf
acoshl
acosl
asinhf
asinhl
asinl

coshl

Also, the following symbols are in vax libm but not in amd64 libm (possibly only relevant on vax, or possibly extraneous internal symbols that shouldn't have been exposed):

d_cbrt
d_sqrt
dcbrt_
infnan
z_abs
