I don't really have a good idea on how to do it nicely. Perhaps try to
fix kernel on 64-bits?

We just default to ":localtime" if TZ is not defined:
http://git.alpinelinux.org/cgit/aports/plain/main/musl/2001-default-to-localtime-timezone-if-TZ-is-undefined.patch

and we make /etc/zoneinfo/localtime a symlink to (or a copy of) the
wanted timezone. Works perfect.

Proper backtrace from core dumps of dynamic linked apps. At least to
get analyzing core dumps working. I think adding CFI is 90% of this.
But IIRC, gdb does not reliably detect mappings of shared objects. That
might need something additional.

thread_db support would be also nice, but that falls into gdbing
running processes.
