macOS /w Xcode 15: force the old linker when targeting macOS 11 or lower
the new linker has problems with weak symbols and causes runtime crashes when
trying to run those builds on older versions of macOS
https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes#Linking
they write the classic linker will be removed in a future release, so have it
error out for Xcode 16 for now just in case. The brave soul who tries it out
first will have to disable that AC_MSG_ERROR… (or expliticly set macOS 12 as
min target)
