Over the weekend just past the upstream PCP CI build on rawhide started failing.  Chatting to Florian he suggested its most likely to be related to binutils, so lets start here.

The link failure is in code that has not changed for a few years - https://github.com/performancecopilot/pcp/tree/14033a5492e8e671b00170a6d5d3235df3b10da9/qa/perfevent - when linking the 'perfevent_test' binary the following link error results:

and build steps described in INSTALL.md (building from source).  Note this failure is in the regression tests, source is below ./qa in the top level.

Reproducible: Always
