I'm having trouble building it from:

[acme@quaco 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=

[acme@quaco perf]$ ls -la perf-5*
ls: cannot access 'perf-5*': No such file or directory
[acme@quaco perf]$ make perf-tarxz-src-pkg ; ls -la perf-5.*
