    Ping: Make build reproducible
    
    As recently fixed in sockstat (9934558460e4), having tests/Makefile
    include files from the parent directory with SRCS= ../foo.c results
    in a race condition as the parent build and the tests build try to
    produce the same object file but contain different paths.
    
    Use .PATH to tell make to find sockstat.c in the parent directory
    but place the object file in the current object directory.
