And you said its value was ../myinstalldir, which cannot possibly
happen unless you set this variable directly from the command line.

It's not a bug: when this variable is not set explicitly on the Make
command line, it should indeed be empty.

If DESTDIR is not empty, it means you have set it.

Better try the patch suggested by Juanma.
