New issue by oreo639 on void-packages repository

https://github.com/void-linux/void-packages/issues/41159

Description:
<!--
  if you are creating a bug report or package request, please fill out one of the forms here:
  https://github.com/void-linux/void-packages/issues/new/choose

  Don't request an update of a package, We have a script for that:

  However, a quality pull request may help.

This was something noticed by sgn and I when debugging the ldc crash on musl when testing the gcc 12 update.
When a segfault occurs, instead of printing the stack trace, libexecinfo either returns 0 or segfaults. (ultimately not really accomplishing anything)

This is something that was noticed in Alpine as well:
https://gitlab.alpinelinux.org/alpine/aports/-/issues/10896

Alpine came to a decision between either fixing libexecinfo or removing it:
https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/36722

They chose the latter as they felt it wasn't useful for the end user and there was no loss of functionality vs staying with the broken libexeinfo.
https://gitlab.alpinelinux.org/alpine/aports/-/commit/50795a14dee639ce2dcc836e2b2baca9bad4a1b1

There is also a supposedly fixed version libexecinfo using libelf here:
https://git.ddd.rip/psykose/libexecinfo

The downside of using this implementation is that the abi is different meaning that all applications using libexecinfo will need to be recompiled. I also haven't tested it, so I can't confirm how well it works or if there are other considerations.
