Looks like get_section is also called for CTORs and 'decl' isn't very well
named.

Hm, we build Ada for riscv64 and it seems fine:

This should already be fixed.  I ran into the same problem in my testing and
committed a patch today that HJ helpfully pointed at.  I don't test ada builds
normally.  I can try that to verify.

My bootstrap with ada succeeded.  I used the same configure options except for
--prefix.  make check is still running.
