build: implicitly configure board and subtarget options

Browse Source 
The file targets/$GLUON_TARGET/config becomes optional, as many targets
only used it to set the board and subtarget.

Also fix targets without subtarget.

A directory for the new target must be created under ``targets``, and it must be added
to ``targets/targets.mk``. In the new target directory, three files must be created:
to ``targets/targets.mk``. In the new target directory, the following files must be created:
* config
* profiles.mk
* vermagic
* config (optional)
The file ``config`` can be used to add additional, target-specific options to the OpenWrt config. It
must at least select the correct target and subtarget. For ``profiles.mk``, see :ref:`hardware-adding-profiles`.
For ``profiles.mk``, see :ref:`hardware-adding-profiles`.
The file ``config`` can be used to add additional, target-specific options to the OpenWrt config.
The files ``vermagic`` must have the correct content so kernel modules from the upstream repositories
can be installed without dependency issues. The OpenWrt version a Gluon release is based on is defined by the upstream package repo URL in ``include/gluon.mk``

As the kernel package is called ``kernel_3.10.49-1-0114c71ed85677c9c1e4911437af4743_ar71xx.ipk``, the correct ``vermagic`` string
is ``0114c71ed85677c9c1e4911437af4743``.
After this, is should be sufficient to call ``make GLUON_TARGET=<target>-<subtarget>`` to build the images for the new target.
