[Debian-med-packaging] Bug#1106652: Bug#1106652: phyml FTCBFS: cross compilation support reverted

Good day Gents,

I'm fine with both outcomes.  I know I have a slight tendency to
fix build failures on 32-bit when issues are somewhat manageable
but dropping 32-bit support would be less work for the team as a
whole on the long term.  If the former option is helpful to
Helmut and the general quality of mpich, perhaps it's worth to
give 32-bit a chance?

Quoting Helmut:

I agree to leave the question rest until stabilisation of trixie
and implement one of the options at the begining of Debian 14
release cycle.

Have a nice day,  :)
