>Description:
gmake has slightly different semantics for ifdef/ifndef, the variable
tested *has to* have a value to be treated as defined.

`ifdef VARIABLE-NAME'
     The `ifdef' form takes the _name_ of a variable as its argument,
     [...]
     The value of that variable has a non-empty value, the TEXT-IF-TRUE
     is effective; otherwise, the TEXT-IF-FALSE, if any, is effective.
`ifndef VARIABLE-NAME'
     If the variable VARIABLE-NAME has an empty value, the TEXT-IF-TRUE
     is effective; otherwise, the TEXT-IF-FALSE, if any, is effective.
>How-To-Repeat:
$ make install deinstall NOPORTDOCS= PREFIX=/foo
$ find /foo ! -type d
