[svn-r3037] Purpose:
	Bug-ish fix
Description:
	Spurious warnings would show up if libtool was trying to pass the
	-LANG:std flag to the compile line.

	Also, if the library is compiled with -all-static, then it would
	complain about not finding dlopen and friends.
Solution:
	Used the libtool -Wc,<flag> option to pass the -LANG:std flag to
	the compile line.

	Used ``-dlopen self'' when compiling.
Platforms tested:
	Linux
