One independent thing to try:
Check make menuconfig of your kernel if any floating point emulation

Floating point emulation ---> [*] NWFPE math emulation
Dirk -
Thanks for this suggestion - I would never have figured that one out. I
had a different floating point emulation implementation selected, and
when I switched to NWFPE things started working.

Can I ask why you
suspected floating point emulation?
Had a similiar issue some weeks ago ;) The switch from kernel (no
floating point at all) to user space (heavily using floating point,
depending on toolchain & library) is always a tricky thing cause you
get *no* debugging output. Things simply do not work :( I think to
remember that default kernel config of git kernel has no floating
point emulation enabled at all.
That an other FPE don't work is new to me, never tried others ;) Maybe
you like to ask on arm-linux list regarding this. Would be an
interesting question.
Regards
Dirk
