[svn-r3029] Purpose:
	Bug Fix
Description:
	Some platforms, when building static libraries, complain that
	libc doesn't have dlopen and friends.
Solution:
	libtool supports workarounds for this. The one used here may not
	work, but it's an attempt to correct it. If it doesn't work, then
	there's something going on which I'm not privvy to...
Platforms tested:
	(untested as of yet)
