Similar to patch 593993, RISC-V needs to limit symbols send in sdata.

Thanks, I committed this as it's just a RISC-V option. Looks like your author-name field is just set to your username in git, I fixed it up based on some older commits (though I missed that last time, sorry).
Might be worth putting together some sort of DG support for these, there's a handful of ports that have sdata-flavored sections and we're all chasing around these test failures.
