OpenBSD doesn't use ld.so for static pie.
This diff might fix the problem. This diff was in one of my ports
trees, but I forgot about it. The diff was from j@bitminer.ca in
"fix GCC 8.4.0 to unbreak -static linking" [1], except that this one
also edits patch-gcc_config_rs6000_openbsd_h for powerpc. I forget if
it works, so I will begin rechecking it.
