How to descend into the extract to build in a subdir

[Paul Schmehl]

I'm working on a port that requires a separate ./configure and ./make to 
build libraries before you build the main source.  How is this done in 
ports?

I figure you have to do something in pre-build:, but I'm not sure exactly 
what.
(cd ${WRKSRC}/subdir && ${MAKE}) causes make to fail entirely.  I'm having 
trouble finding a comparable example in ports and there doesn't seem to be 
anything about it in the porters handbook (that I have found.)
