Thank you for this information. I have trouble finding definitive
documentation for Apple development tools.
My original patch assumes that `-no_fixup_chains` would be silently ignored by
intermediate linker versions older than Xcode 13. I have not yet tested this
assumption on any such Macs.
If that is a good assumption, then existing guards in the current 2.4.7
libtool code block should be sufficient, and I recommend merge with no
changes.
If not a good assumption, or it goes against GNU libtool design standards in
any way, such as no unknown flags, then I request help on how to construct the
correct test within libtool, for the Xcode linker version.
