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):

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
