Log Message:
Mark as using c language. This fix PLIST problem while doing
'make package' (make; make package works): without this SHLIB_TYPE
is set to 'none' while doing 'make package', resulting in
mk/plist/shlib-none.awk being used hence missing PLIST entries.

XXX I suppose this may not really be the right fix (barrier
problem?) but for the time being 'pkg_comp makeroot' succeed

XXX What is this 'foo' target?
