It appears that scons implicit dependency scanners fail to chain
dependencies of generated headers when these are outside the build tree.
This patch ensures generated source files are _always_ put in the build
tree. I'm not 100% this will fix all depency issues, but from my
experiments it does seem to fix this.
NOTE: For this to be effective it is necessary to clean the source tree
from generated header/source files.
