Build of bpf and tc-testing selftests fails when the relative path of the build directory is specified.

The fix is same as mentioned in commit 150a27328b68 ("bpf, preload: Fix build when $(O) points to a relative path").
I don't think it actually helps building BPF selftest. Even with this
This patch is fixing one type of build error which occurs if output directory's path is relative.
patch applied, all the feature detection doesn't work, and I get reallocarray redefinition failure when bpftool is being built as part of selftest.
There may be more problems in BPF tests. Those needs to be looked at separately.
