The Makefile verifies the same file exists twice:
  test -f ../../../include/uapi/linux/bpf.h -a \
       -f ../../../include/uapi/linux/bpf.h

The purpose of the check is to ensure the diff (immediately after the
test) doesn't fail with these two files:

  tools/include/uapi/linux/bpf.h
  include/uapi/linux/bpf.h

Same recipe for bpf_common:
  test -f ../../../include/uapi/linux/bpf_common.h -a \
       -f ../../../include/uapi/linux/bpf_common.h

This corrects the location of the tests.
