lang/gcc: drop riscv64 hack

The hack below was sufficient to let lang/gcc build using llvm-13, but
wasn't enough anymore since llvm-16, so I worked around the
gcc_except_table problem in ld.lld instead. The hack can now be cleaned
up. The REVISION bump probably doesn't bring much but can't hurt.

ok?
