394053f4a4b3 ("kbuild: make single targets work more correctly")
changed the way single target builds work. For example,
'make samples/bpf/' in the previous commit matched:
Makefile:1787
%/: prepare FORCE
$(Q)$(MAKE) KBUILD_MODULES=1 $(build)=$(build-dir) need-modorder=1
So that 'samples/bpf/Makefile' was processed directly.
Commit 394053f4a4b3 removed this rule and now requires that
'CONFIG_SAMPLES=y' and that 'bpf/' be added to 'samples/Makefile'
so it is added to the list of targets processed by the new
'ifdef single-build' section of 'scripts/Makefile.build'.
This commit adds a new 'CONFIG_SAMPLE_BPF' under 'CONFIG_SAMPLES' to
match what the other sample subdirs have done.
