Dear maintainers,
librandom123 does not enable riscv64 build by default, which caused FTBFS on
packages like neuron:

Full buildd log of neuron:
https://buildd.debian.org/status/fetch.php?pkg=neuron&arch=riscv64&ver=8.2.2-2&stamp=1675434052&raw=0
I've successfully built neuron on riscv64 by adding macro condition to bypass
manual compilation error, as shown in the attached patch. If more help is
needed, please let me know.
Cheers,
Eric
