Use `have-lib' when checking for libltdl.
Suggested by primus <rprimus@gmail.com>.
* configure.ac: Use `AC_LIB_HAVE_LINKFLAGS' when checking for libltdl.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_LIBADD):
Add $(LTLIBLTDL).
* README: Update to make it clear that libgc and libffi don't have a
`--with-XXX-prefix' option.
