binutils-gdb/ld/configure.in
Ian Lance Taylor 2e5983457a * configure.in: Look for --enable-shared. Change the value of
BFDLIB when linking against a shared library on SunOS.
	* configure: Rebuild.
	* configure.host: If using a shared BFD library, try to pass a
	reasonable -rpath option when linking.
	* Makefile.in (BFDLIB): Set to @BFDLIB@.
