XL: Move '-bE' flag earlier so it can be overridden

Browse Source 
By default, we generate an export list for a shared library and pass
that file on the link line.  The problem was that it could not be
overridden by a target when a specific export file is being used.
Multiple `-bE` flags on the link are overridden by subsequent `-bE`
flags, so only the last one is used.

Fixes: #13282
