[PATCH] _make-parseMakefile: skip non-targets

[Daniel Hahler <genml+zsh-workers@xxxxxxxxxx>]

From: Daniel Hahler <git@xxxxxxxxxx>

These look like this, and might come from pattern rules ("%.res" in this
case):

    # Not a target:
    test_autocmd.res:
    #  Implicit rule search has not been done.
    #  Modification time never checked.
    #  File has not been updated.
