OK, it seems to have to do with an object changing from a simple build
to a multi object build.

i.e. Tuesday's linux-next has these changes:

 obj-$(CONFIG_CRYPTO_USER) +=3D crypto_user.o
+crypto_user-y :=3D crypto_user_base.o crypto_user_stat.o
 obj-$(CONFIG_CRYPTO_CMAC) +=3D cmac.o

 obj-$(CONFIG_I2C_HID)				+=3D i2c-hid.o
+
+i2c-hid-objs					=3D  i2c-hid-core.o
+i2c-hid-$(CONFIG_DMI)				+=3D i2c-hid-dmi-quirks.o
