perf tools: Do not check ABI headers in a detached tarball build
When we use one of:
[acme@jouet linux]$ make help | grep perf
perf-tar-src-pkg - Build perf-4.14.0-rc3.tar source tarball
perf-targz-src-pkg - Build perf-4.14.0-rc3.tar.gz source tarball
perf-tarbz2-src-pkg - Build perf-4.14.0-rc3.tar.bz2 source tarball
perf-tarxz-src-pkg - Build perf-4.14.0-rc3.tar.xz source tarball
[acme@jouet linux]$
I.e. when we create a detached tarball to build perf outside outside the
enveloping kernel sources (from a kernel tarball or a checked out
linux.git directory) we by definition can't check for differences among
the tools/{include,arch}, etc files we originally copied from the
kernel, so bail out in that case, to avoid warnings when doing the
detached builds.
