>Description:
        
pkg-build-options.mk fails with the following error when a package was
built with no options selected.

The reason is that make cannot handle it when the command for a != operator
returns no output at all.  AFAIK, this behaviour has been there about forever.

>How-To-Repeat:
        
cd pkgsrc/devel/libgnomeui && make -n update 2>&1 | sed 4q

>Fix:
        
Maybe produce some dummy output as the first line and remove it from
the variable in a second step.
