Backport link test fix from upstream Libtool: 

* libltdl.m4 (_LT_SYS_DYNAMIC_LINKER, _LT_LINKER_SHLIBS):
	Add cache variables to tests that require the linker to work.
	For shlibpath_overrides_runpath, this also changes the semantics
	to let the result from the C compiler take precedence.
	compiler take precedence.
