[Bug 2081848] Re: fix underlinking with recent LLVM 18.1.8 backport

[Chris Siebenmann]

This issue makes all of our bpftrace based observability tools non-
functional on our Ubuntu 24.04 machines, taking out important
troubleshooting ability. How did this package pass testing for an Ubuntu
24.04 SRU given that its bpftrace binary doesn't even run on an Ubuntu
24.04 machine?

(Yes I know we can revert bpftrace back to the original released version
and then hold it against any further updates. Or rebuild this package
from source on Ubuntu 24.04 since a from-source rebuild of the source
.deb on 24.04 does produce a working binary.)

Title:
  fix underlinking with recent LLVM 18.1.8 backport

Status in bpftrace package in Ubuntu:
  Confirmed
Status in bpftrace source package in Noble:
  Fix Released

Bug description:
  An archive test rebuild with a planned LLVM 18.1.8 showed up one regression, building bpfrace.  The issue however is in bpftrace itself, and is already fixed in oracular 0.21.0-1ubuntu1.
  Another backport is from 0.21.0-1ubuntu5, ignoring the unknown .debug_addr section in dh_dwz on armhf.

  Testing done for that patch: The package builds with the backported
  18.1.8 package and passes its tests.
