audio/espeak doesn't build on sparc64 due to what looks like a bug
in either base libtool or ld.bfd. libtool eats -L options for the
ld.so search directories in the ldconfig -r output, which then causes
linking failures:

The below works around this. We could also switch to unconditional
USE_LIBTOOL = gnu (and bump REVISION, I guess).

This depends on the dwz fix I just committed.
