2.32 also brings in 64-bit time_t/offset support (at least the ARC ABI
is) so there might be even more work in rest of ecosystem.

At one point you were contemplating diff'ing between glibc 2.31 and 2.32
and trying to apply that to unstable package w/o bumping the version.
But how about we take 2.31 as baseline and use the prio ARC port (same
32-bit time_t ABI) to kick things forward if just as a hack. We would
then be able to shake out any other potential downstream blockers)

Thx, that is appreciated.

Noted.
