Currently the following command produces an error message:
linux# make kselftest TARGETS=bpf O=/mnt/linux-build
# selftests: bpf: test_libbpf.sh
# ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
# test_libbpf: failed at file test_l4lb.o
# selftests: test_libbpf [FAILED]
The error message might not affect make return code, therefore one might
need to grep make output in order to detect it.
The current logic prepends $(OUTPUT) only to the first member of
$(TEST_PROGS). After that, run_one() does
cd `dirname $TEST`
For all tests except the first one, `dirname $TEST` is ., which means
they cannot access the files generated in $(OUTPUT).
Fix by using $(addprefix) to prepend $(OUTPUT)/ to each member of
$(TEST_PROGS).
