416.gamess requires -funconstrained-commons

This issue is just for bookkeeping; I'm not sure where else to put it. The benchmark is buggy and it fails with recent GCCs on other platforms, too: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69368

-funconstrained-commons is a relatively new flag. For very old GCCs, -fno-aggressive-loop-optimizations seems to suffice. For GCCs in the middle, I don't have a good workaround.

Thanks, if you find the flag(s) that works for RISC-V tools, those flags should be placed in the portability section of the configuration files: https://github.com/ccelio/Speckle/blob/master/riscv.cfg#L134

They can then sit in the corner with perlbench's std=gnu89 and think about what they did.
