python313 (2025Q4) fails to build (link) on hppa -current

[vom513 <vom513%gmail.com@localhost>]

Hello all,

Trying to build packages from 2025Q4 on my hppa machine running a -current from a few days ago.  python312 built fine previously (older -current, 2025Q3).

It seems to compile everything but the linking at the end is where it chokes.  Any ideas ?
