How exactly are you specifying this flag, and what exactly happens?

Because they're likely to be non-PIC, and several platforms don't
support non-PIC in shared libraries.  If Darwin does, all you have to
do is to post a patch that sets deplibs_check_method=pass_all.

Compile it as a libtool convenience archive.  That's exactly the
purpose of this feature.
