What makefile change caused this? That behavior doesn't make much sense
given how make processes its command-line arguments.
I agree with you here, it could be a rare check where one want to define
what collect progam should be used ( ld or ar )
besides, recently we moved AR to be gcc-ar/llvm-ar by default in config
metadata, which is not going to work out of box for compiling kernel and
modules, so overriding it with KERNEL_AR in
module_do_compile/install/configure tasks is good change.

The 5.x kernels seem to have made a change to the linker command
line processing.
When trying to build out of tree kernel modules, such as the
virtualbox guest additions, the following error is printed:

The AR arguments passed to the make command are being processed as
command line arguments to the linker due to some changes in the
kernel's Makefile. For now the easiest fix is to just swap the
arguments in the module.bbclass.
