When a computer does not boot at all or the result is only a deep black screen,
a very useful option can be to use a serial connector to get UART debug console
and read it, looking for any useful hint. However, enabling UART debug console
with a sufficient level of details slows down the boot process in most cases.
This commit adds the capability to build debug images, using a special
configuration file for coreboot with debug options. This is a simplistic way
that works for now, but should be improved later on.
These debug images will be generated in the bin-dbg/ directory instead
of bin/ where regular images are located.
