Hi,

In my latest build I created an OVERRIDE in debian/rules for dh_dwz as
this seems to have problems with DWARF-v5.
dh_strip_nondeterminism ... passed
dh_dwz ... SKIPPED
dh_strip ... passed
^^ Build OK

At 99% when linking the quassel binaries I see /usr/bin/ld -
GNU/binutils LD linker - is used (via ps -ef).
This uses DWARF Level 4 as default (gas/as.c file in the sources).
This is binutils 2.43.1 in Debian/unstable.
Looks like I have to force the usage of LLD linker somehow.

In Linux-kernel we pass -Wa.-dwarf-5 to the assembler.
Clang (Clang++ ?) uses an Integrated ASsember (IAS).
Maybe, I need to pass -gwarf-5 plus -Wa.-dwarf-5 to CC and CXX lines?

If someone has an idea, please let me know.

Might be dh_dwz (dwz) is simply BROKEN with DWARF-v5.

Best thanks.
