From: Björn Töpel <bjorn.topel@xxxxxxxxx>
This commit makes it possible to build the BPF samples via a Kconfig
option, CONFIG_SAMPLE_BPF. Further, it fixes that samples/bpf/ could
not be built due to a missing samples/Makefile subdir-y entry, after
the introduction of commit 394053f4a4b3 ("kbuild: make single targets
work more correctly").
