Using configure and make on AIX, nothing seems to set OMR_ENV_OPENXL

I'm using OMR 4.0.

The configure script now detects that ibm-clang should be used. However, nothing seems to set OMR_ENV_OPENXL, so when using make to build the code it now fails with:

It seems to be using the open XLC compiler but with the flags for the old xlc compiler.
