Therefore, the modules can be selected as built-in even if the BT=m. The combination of BT=m and =y for the said modules leads to the kernel build system silently ignoring those modules, without ever compiling them as built-in or as loadable modules. Add BT as a direct dependency to the Kconfig of rfcomm, bnep, hidp, and bluetooth_6lowpan. The modules set to =y when BT=m will default to =m, rather then getting silently ignored by the build system.
