Andrew Tridgell 3921d6f4d3 s4-waf: automatically remove stale C and header files
this prevents stale .c and .h files in bin/ from causing build
problems

Thanks to Thomas Nagy for the example implementation!

"""
Add a pre-build hook to remove all build files
which do not have a corresponding target
This can be used for example to remove the targets
that have changed name without performing
a full 'waf clean'
Of course, it will only work if there are no dynamically generated
nodes/tasks, in which case the method will have to be modified
to exclude some folders for example.
