KUnit's 'hooks.o' file need to be built-in whenever KUnit is enabled (even if CONFIG_KUNIT=m). We'd previously attemtped to do this by adding 'kunit/hooks.o' to obj-y in lib/Makefile, but this caused hooks.c to be rebuilt even when it was unchanged.
Instead, always recurse into lib/kunit using obj-y when KUnit is enabled, and add the hooks there.
