Build the Bullet Physics Python bindings for riscv64. setup.py compiles the Bullet3 C++ sources directly into the pybullet and eglRenderer extension modules; every SSE and x86 asm path is already gated on __i386__/__x86_64__, so no patch is needed. 3.2.7 was released without a git tag, so the workflow pins the release commit; its tree is byte-identical to the PyPI sdist. pybullet.c hands PyObject* to numpy's PyArrayObject* accessors. GCC 13, which upstream's manylinux2014 image ships, only warns; the GCC 14.3.1 in manylinux_2_39_riscv64 makes -Wincompatible-pointer-types a hard error, so the build passes -Wno-error for it.
