imake / xorg build error

[Sam Lawrance]

In case anybody else comes across this error in devel/imake-6 (and  
other xorg ports):

The problem was that I was running a release built with RELEASENAME  
set to something not matching the usual form (eg RELEASENAME=blah vs.  
RELEASENAME=6.0-STABLE).  It seems that xorg uses that string for  
some pre-build configuration.

I used a faked-up uname from ports/Tools/portbuild/5/bindist/usr/bin/ 
uname as a workaround.
