If anyone has any objections, please let me know. ------------------ From: Sasha Levin commit 52336337f1a01ad803c7f3ddb23f40222e9ad58d upstream. "make O= tools/gpio" fails: Makefile:27: /tools/build/Makefile.include: No such file or directory tools/Makefile clears srctree, and the gpio Makefile only works it out again when building_out_of_srctree is not set, which the top-level Makefile sets for O= builds. Also work out srctree when it is empty, as tools/bpf/Makefile does since commit a89b2cbf71d64 ("tools, bpf: Fix build for 'make -s tools/bpf O='").
