My solution to this issue:
Add riscv64 support for this package. I have completed the development of
the patch for supporting the riscv64 architecture.I have tested this patch
on local, and it works well.The debdiff patch is in the attachment.Please
let me know wheather this sotution can be accepted.

Hi Yue,

Thanks a lot for analyzing the issue and proposing a patch to implement
riscv64 support. It would be best to propose the support extension
upstream to epics-base developers. This would not only reduce the
Debian-specific overhead, but might as well be beneficial to epics-base
developers. Could you forward the patch to them please?

Best wishes,
Andrius
