Yeah, that is the simplest fix for now. Lets just go with it.
Could you also take a peek at the Debian workaround for dealing with
arches that don't support perf?
https://salsa.debian.org/toolchain-team/elfutils/-/commit/2cd08fdcfcaf15d6a2b7b085faedadfc94a4729c
I am not sure just listing all the arches that don't support perf is
really the way to go. But maybe it is the best there is?
