    piglit: fix build failure with gold linker
    
    When we use gold linker while DISTRO set to "nodistro", piglit build
    fails with the following error:
    
    | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to
    'dlsym'
    | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to
    'dlerror'
    | ../../../../lib/libpiglitutil_gl.so.0: error: undefined reference to
    'dlopen'
    | collect2: error: ld returned 1 exit status
    
    Fix it by providing '-ldl' to LDFLAGS.
