Compiling python on 32 bit ARM

Hi,

I've got two systems here that run netbsd-10 earmv7hf and earmv6hf. Both, 
coincidentally, can't finish compiling python, either python312 (earmv7hf) 
or python313 (earmv6hf):

Compiling '/usr/pkgsrc/lang/python313/work/.destdir/usr/local/lib/python3.13/test/pickletester.py'...

   PID USERNAME PRI NICE   SIZE   RES STATE       TIME   WCPU    CPU COMMAND
29683 root      25    0    26M   18M RUN         9:59 98.05% 98.05% python

SIGINFO gives:

[ 3478085.4966587] load: 1.19  cmd: python 29683 [0x78d76088] 597.46u 6.05s 97% 18680k

Doesn't respond to control-c.

Same with earmv7hf:

   PID USERNAME PRI NICE   SIZE   RES STATE       TIME   WCPU    CPU COMMAND
18404 root      21    4    28M   18M CPU/1      12:05 99.02% 99.02% python
12853 root      21    4    33M   23M CPU/2      12:04 99.02% 99.02% python
  9894 root      21    4    31M   21M RUN/3      12:02 98.78% 98.78% python
14960 root      21    4    25M   16M CPU/0      12:01 97.02% 97.02% python

All are stuck in "mult":

   Id   Target Id                   Frame
* 1    LWP 9894 of process 9894 "" 0x74cd5f40 in mult () from /usr/pkgsrc/lang/python312/work/Python-3.12.8/libpython3.12.so.1.0

Any ideas about what's going wrong here?
