In section 6.11:
Target-specific variable assignments can be prefixed with any or all of the
special keywords export, override, or private; these apply their normal
behavior to this instance of the variable only.
the way I read it is that you can specify one or many special keywords. If I
try to use 2, I get an error message. As soon, as I remove one of them, make
works as expected.
Maybe it is the wording that is misleading the 'any or all' may be meaning
'none or any one of the special keywords'.
