libbpf: Fix up generation of bpf_helper_defs.h
$ make -C tools/perf build-test
does, ends up with these two problems:
make[3]: *** No rule to make target '/tmp/tmp.zq13cHILGB/perf-5.3.0/include/uapi/linux/bpf.h', needed by 'bpf_helper_defs.h'. Stop.
make[3]: *** Waiting for unfinished jobs....
make[2]: *** [Makefile.perf:757: /tmp/tmp.zq13cHILGB/perf-5.3.0/tools/lib/bpf/libbpf.a] Error 2
make[2]: *** Waiting for unfinished jobs....
Because $(srcdir) points to the /tmp/tmp.zq13cHILGB/perf-5.3.0 directory
and we need '/tools/ after that variable, and after fixing this then we
get to another problem:
/bin/sh: /home/acme/git/perf/tools/scripts/bpf_helpers_doc.py: No such file or directory
make[3]: *** [Makefile:184: bpf_helper_defs.h] Error 127
make[3]: *** Deleting file 'bpf_helper_defs.h'
LD /tmp/build/perf/libapi-in.o
make[2]: *** [Makefile.perf:778: /tmp/build/perf/libbpf.a] Error 2
make[2]: *** Waiting for unfinished jobs....
Because this requires something outside the tools/ directories that gets
collected into perf's detached tarballs, to fix it just add it to
tools/perf/MANIFEST, which this patch does, now it works for that case
and also for all these other cases.
Fixes: e01a75c15969 ("libbpf: Move bpf_{helpers, helper_defs, endian, tracing}.h into libbpf")
