This reverts commit a672af9139.
By now it is not used for building tools/perf, but Stephen Rothwell
reported that when building on a O= directory that had been built with
torvalds/master and this perf build command line:
$ make -C tools/perf -f Makefile.perf -s -O -j60 O=/home/sfr/next/perf NO_BPF_SKEL=1
If we then merge perf-tools-next, as he did for linux-next, then we end
up with a build failure for libbpf:
PERF_VERSION = 6.9.rc3.g42c4635c8dee
make[3]: *** No rule to make target '/home/sfr/next/next/tools/include/uapi/linux/stat.h', needed by '/home/sfr/next/perf/libbpf/staticobjs/libbpf.o'. Stop.
make[2]: *** [Makefile:157: /home/sfr/next/perf/libbpf/staticobjs/libbpf-in.o] Error 2
make[1]: *** [Makefile.perf:892: /home/sfr/next/perf/libbpf/libbpf.a] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile.perf:264: sub-make] Error 2
This needs to be further investigated to figure out how to check if
libbpf really needs something that is in that
tools/include/uapi/linux/stat.h file and if not to remove that file in a
way that we don't break the build in any situation, to avoid requiring
doing a 'make clean'.
