Yo!

With the release of pacman 6.0.2 we have now support for debug packages through
`debugedit` as opposed to the awk hack used previously.

Checking arch-rebuild-order-debug-0.3.1-1-x86_64.pkg.tar.zst

arch-rebuild-order-debug W: Directory (usr/src/debug) is empty


Seems the source is missing:

Testing with rust-gdb:

rust-gdb --args arch-rebuild-order opencolorio

My local cargo build works fine with the same commands:

Not sure, what's going wrong with the debug build.

I removed my testing chroot in /var/lib/archbuild and rebuild arch-rebuild-order.
