I really can't see any reason why it should be doing that,
specially if you're already using libtool.  I suggest you
either don't call AC_LIB_HAVE_LINKFLAGS or get
AC_LIB_HAVE_LINKFLAGS fixed not to do that.

AC_LIB_HAVE_LINKFLAGS seems to be in
/usr/share/aclocal/lib-link.m4 which is part of gettext.
