>Description:
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

atanhl
atanl
cabsf
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
>How-To-Repeat:
build mesa
>Fix:
Yes, please!

 Log Message:

 But leave a replacement xfail test that fails unconditionally, to
 leave a reminder in the tests of PR 57881: vax libm is missing
 various symbols.

 Log Message:

 While here, make sin, cos, and tan be weak aliases for internal
 symbols _sin, _cos, and _tan; likewise sinf, cosf, tanf.

 Log Message:

 While here, delete #ifdef to handle ns32k -- I don't think that's
 gonna be relevant any time soon; in case you hadn't noticed, the
 world has moved on from ns32k to vax by now.
