    unarr, build: Quell Automake warning
    
    cut-n-paste/unarr/Makefile.am refers to sources in subdirectories.
    Option "subdir-objects" tells Automake to put the compiled objects in
    the same directory as the source file.  Without this option Automake
    prints warnings related to forward compatibility.
