Log Message:
emacs25: Do not (manually) inject X11 LDFLAGS via configure

On NetBSD and OpenBSD the configure script injects LD_SWITCH_X_SITE_RPATH
(e.g.  `-Wl,-rpath,/usr/X11R7/lib') early as LDFLAGS leading to link with
possible X11 native libraries when it is not requested.

Should fix PR pkg/53688.

Bump PKGREVISION

Thanks to <maya> for debug-fu help!
