proposed migration for genx 3.6.21-1

[Vladimir Petko]

The package is missing builds on :
- arm64 (core dump)
- armhf (python error)
- s390x (python error)
- riscv ( dependency wait on numba package )

Numba package failed to build for riscv:
------------
 Running Sphinx v5.3.0
WARNING: This target JIT is not designed for the host you are running. If bad things happen, please choose a different -march switch.
LLVM ERROR: Unsupported code model for lowering
Fatal Python error: Aborted
----------

[Vladimir Petko (vpa1977)]

riscv error is caused by llvmlite package which depends on llvm-14 that in turn does not fully support riscv JIT[1]

Debian has dropped genx binaries in unstable on all archs except for amd64 and ppc64el, we should do the same.
