Darwin : Update libtool and dependencies for Darwin20 [PR97865]

The change in major version (and the increment from Darwin19 to 20)
caused libtool tests to fail which resulted in incorrect build settings
for shared libraries.

	PR target/97865
	* libtool.m4: Update handling of Darwin platform link flags
	for Darwin20.
