We can't straight-up patch boost because it has too many dependants, but
I copied the configure phase to boost-for-mysql and applied the changes
there.

It built with no problems with python2 instead of python3 but of course
I'd rather not add more dependencies on python2. Luckily it will build
without any python binaries so I've just gone ahead and removed python
