scipy fails to load with glibc-2.39

this is fixed by the scipy no-change rebuild. maybe add breaks for glibc?

[Simon Chopin (schopin)]

Fair enough, will do in the next upload. I'm a bit confused though, as GLIBC_2.39 *is* in libm.so.6 according to readelf:

noblerun readelf -W -s /lib/x86_64-linux-gnu/libm.so.6 | grep 2\\.39
   578: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS GLIBC_2.39
  1074: 0000000000033410 590 FUNC GLOBAL DEFAULT 18 exp10@@GLIBC_2.39

This bug was fixed in the package glibc - 2.39-0ubuntu6

---------------
glibc (2.39-0ubuntu6) noble; urgency=medium

  * Renable CET on x32 from i386 again as it may not work but disabling breaks
    the build.
