ar rcs pyml-current/libpyml_stubs.a pyml-current/pyml_stubs.o
/usr/local/bin/ocamlmklib -linkall -o pyml-current/pyml_stubs pyml-current/pyml_stubs.o pyml-current/libpyml_stubs.a

fails, but this works
ar rcs pyml-current/libpyml_stubs.a pyml-current/pyml_stubs.o
mv pyml-current/libpyml_stubs.a /tmp/
/usr/local/bin/ocamlmklib -linkall -o pyml-current/pyml_stubs pyml-current/pyml_stubs.o /tmp/libpyml_stubs.a

backporting part of 'Fix Makefile dependencies'
https://github.com/coccinelle/coccinelle/commit/3f93bfbb207b8e73f5f39afdf1c6f4a96038d2e4
works with llvm-ar here
