Ports failing with bsd make

On recent -current, several ports are failing to build. Common quality: They 
all use the system make rather than gmake.

Examples: science/hdf, textproc/Wordnet, devel/qmake.

The errors all look pretty similar:

===> mfhdf/nctest (all)
make: don't know how to make nctest.1. Stop
...

make: don't know how to make wn.1. Stop
...

make: don't know how to make qmake.1. Stop

Looks like they're all failing while trying to generate manpages. Has make 
become allergic to targets with a dot in them perhaps?
