perf tools: Fix 'make tools/perf'
Boris just raised another variant of building perf tools which is broken: $ make tools/perf ... LINK /home/robert/cx/linux/tools/perf/perf gcc: error: ../linux/tools/lib/lk/liblk.a: No such file or directory The variant wasn't considered by: 107de372 perf tools: Fix build errors with O and DESTDIR make vars set There are other variant of building perf too: $ make -C tools perf $ make -C tools/perf Plus variants with O= and DESTDIR set. This patch fixes the above and was tested with the following: $ make O=... DESTDIR=... tools/perf $ make O=... DESTDIR=... -C tools/ perf $ make O=... DESTDIR=... -C tools/perf $ make tools/perf $ make -C tools/ perf $ make -C tools/perf Reported-by: NBorislav Petkov <bp@alien8.de> Signed-off-by: NRobert Richter <robert.richter@linaro.org> Signed-off-by: NRobert Richter <rric@kernel.org> Cc: Borislav Petkov <bp@alien8.de> Cc: H.
