ocaml: Fix test for -runtime-variant _pic.

Browse Source 
This fails with Fedora 32, and possibly earlier versions:

  checking if OCaml ‘-runtime-variant _pic’ works... no

The reason is:

  $ ocamlc -runtime-variant _pic test.ml -o test
  File "test.ml", line 1:
  Error: Cannot find file camlheader_pic

which may even be a packaging error in the Fedora package.  However it
makes no sense to test the bytecode compiler since we don't use it on
any architecture we care about and bytecode doesn't even contain a
linked runtime.  Changing the test to use ocamlopt instead of ocamlc
fixes the problem.
