I'm having trouble building it from:

[acme@...co perf]$ make help | grep perf
  perf-tar-src-pkg    - Build perf-5.3.0-rc6.tar source tarball
  perf-targz-src-pkg  - Build perf-5.3.0-rc6.tar.gz source tarball
  perf-tarbz2-src-pkg - Build perf-5.3.0-rc6.tar.bz2 source tarball
  perf-tarxz-src-pkg  - Build perf-5.3.0-rc6.tar.xz source tarball

I.e. detached tarballs, outside the kernel source tree, also using O=
