So, it fails 'make -C tools/perf build-test', specifically the one where
we ask for a NO_LIBELF build, trying to fix:
- make_no_libelf: cd . && make -f Makefile DESTDIR=/tmp/tmp.AzIgKZ2Y7K NO_LIBELF=1
cd . && make -f Makefile DESTDIR=/tmp/tmp.AzIgKZ2Y7K NO_LIBELF=1
BUILD: Doing 'make -j4' parallel build
