This set of flags was working great until my last build on Oct 15.

nm says that symbol is present in /sw/lib/libcdio_cdda.0.0.3.dylib.
However -lcdio_cdda (or any other of the the cdio lib flags) is not being
added to the linker command --> undefined symbol error.
Git bisect points to 66a1ccd7467ab1913cd8877114c6d4c2588bb12f as the
culprit. But towards the end of the bisect run, it starts giving errors
that configure options are not recognized (Unknown option "--enable-
libass"), which seems more like the bisect command got confused and left
the tree in an unstable mode vs it being the actual culprit (though it
might explain the syntax errors in the original failure).
