Yep, it might be, if there are many more symbols than the ones that
the library actually exports.

libtool does support -export-symbols, that controls symbol exporting,
but it doesn't use this information to construct the dlpreopen symbol
list, only to control the link-time list of symbols exported from a
shared library. This could certainly be implemented in the future.
