Is the rc4 build source path expected?

We should use ${PYTHON_VER} for these, for our future selves when PyPY port supports other Python versions, but that can be done in a separate change

Given the context, it must be correct or else the build would have failed; but I can confirm that the port's build created this path in ${WRKDIR}/build: usession-release-pypy2.7-v7.3.0rc4-0, and the pre-build only creates ${WRKDIR}/build for their build infrastructure to create a directory in.
