Right, when you build tools/perf inside a checked out copy of the kernel
sources, you'll be able to access files outside tools/ and everything
will build just fine.
But tools/ living code shouldn't access anything outside tools/, so when
you do:
[acme@...et perf]$ make help | grep perf
perf-tar-src-pkg - Build perf-4.15.0-rc3.tar source tarball
perf-targz-src-pkg - Build perf-4.15.0-rc3.tar.gz source tarball
perf-tarbz2-src-pkg - Build perf-4.15.0-rc3.tar.bz2 source tarball
perf-tarxz-src-pkg - Build perf-4.15.0-rc3.tar.xz source tarball
[acme@...et perf]$
And grab the resulting tarball (just run ls -lart), extract it, say,
under /tmp/, or in some other machine, and try to build it, it'll fail.
I've fixed this already, please check:
https://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git/commit/?h=perf/core&id=642d3d0964efb216c2823af78147c46913f26804
Doing it this way will also warn us when something changes in the files
used by tools/perf/ that may be of interest to tooling, just like with
the other tools/{arch,include/lib}/ files we copied from the kernel
sources.
