I could reproduce (and fix :-)) this problem.

The solution was to *prepend* instead of appending the source directory of the 
software being
compiled to EMACSLOADPATH, in the 'add-source-to-load-path phase of the
Emacs build system.

Pushed to master with commit add773c37a10e2c900fcfaff745e095b7fe96fbb.

Thank you for the report and reproduction steps.
