[Bug 2086104] Re: bpftrace is broken on Oracular

[Mate Kukri]

This is caused by two copies of LLVM being linked into the bpftrace
binary: both the shared libraryand the static ones.

I guess if these are the same version this doesnt cause issues, but a
later LLVM update left the static one s out of date.

The patch is to change the build process to only link the shared LLVM.
This applies to plucky too, and should be backported to Oracular to
unbreak bpftrace.
