Pybombs can't solve a lack of RAM -- it just offers an automated build procedure. Search google to find information how to add swap to your system. However, swap is just RAM that is temporarily exiled to permanent storage. Now, a microSD card is several orders of magnitude slower than RAM, so whilst that might allow your build process to work, it will make it slow.
