The check for whether the linker supports the -single_module flag assumes that
anything printed to stderr containing the string "single_module" means it is
unsupported. Xcode 15 does print such a message, though it only indicates that
the flag is deprecated. Lack of single module support triggers some
workarounds that aren't needed and don't work very well on modern systems.
This flag has been unnecessary for many macOS versions, so teaching libtool
that it is not needed in this case is probably preferable to just fixing the
check. See attached patch.
