you probably need to delete any compiled thing with

make dirclean

then reinstall all packages from the feeds

./scripts/feeds uninstall -a
./scripts/feeds clean
./scripts/feeds update -a
./scripts/feeds install -a

and then you can recompile.

Otherwise it will just reuse things you have already compiled with 
different options.

As Adrian said, that's more or less what the buildbot also does, each 
time it starts from scratch in a clean build folder.
