The full buildd log is here:
My solution to this issue:
Add a patch(my patch is in the attachment) to add basic support for arch riscv and loong.By the way,I have included the correct header file <cstdint> in the relevant files.Details can be found in the attachment.
I have tested this patch in local, it work effectively, Please let me know wheather this patch can be accepted.
