Here is the thing though: The build system requires you to make a

to specify in the Makefile to put this at the beggining of the
SConstruct file
Hmm, so you're just allowed one file, and that's the Makefile? I see.
That does complicate things a little bit, but it is still doable.
For simplicity, I'll assume you already know how to make it download the
original source file etc., and how to integrate this with the rest of
the makefile, seeing as you're more familiar with the build system than
I am.
I've attached a Makefile that prepends the text I gave earlier to the
SConstruct file before calling scons, and restores the original on
clean. It seems to work for my test project, and should hopefully still
work in a more complex environment.
I believe the same approach can also be used for more complex patches
(assuming the patch command is available on the buildhost), as we could
then define the text on patch format and pipe it to the patch command
instead of directly to file like this does.
