Building perf from the kernel sources is fine, but usually the kernel
packaging takes more time to be completed, more tests, etc and if
someone wants to move the perf tools side of things faster, then using
the tarball may be an option.
Another workflow using the tarball allows is to have different packagers
for the kernel and for the perf tools.
But either way is fine, its just a way to allow more ways to package
perf, to try the latest (or an older one) on an arbitrary kernel or
system with different versions of the libraries it links to.
