You are still adding EXTRA_LDLIBS in a patch called "simplify the
ifdefs".

A good idea before sending a new version of a patch on the mailing
list is to check the list of the modifications that were discussed.
Then this list can be added in the cover letter or after the "---"
marker of your patch, allowing the reviewers to better understand
what changed in this version.

Regards,
Olivier
