FWIW, they are still generically handled by the .vtable_inherit and
.vtable_entry pseudo-ops, but support for -fvtable-gc has been removed
from gcc in 2003.  The RISC-V assembler never picked them up.

$ riscv64-suse-linux-as vtable.s 
vtable.s: Assembler messages:
vtable.s:1: Error: cannot represent BFD_RELOC_VTABLE_ENTRY relocation in object file
vtable.s:2: Error: cannot represent BFD_RELOC_VTABLE_INHERIT relocation in object file
