I hit this FTBFS earlier today while trying to build the LT 4.19.132 kernel from source:

The "quick hack" patch mentioned at the bottom of the thread gets it to compile. Is this the correct solution, or is there a better fix? As it stands, tools/perf doesn't seem to compile on 4.19.132.

No idea, try asking the perf developers.
