Append an extra string to the end of the coreboot version.
This can be useful if, for instance, you want to append the
respective board's hostname or some other identifying string to
the coreboot version number, so that you can easily distinguish
boot logs of different boards from each other.

In the above example 1106 is the PCI vendor ID (in hex, but without
the "0x" prefix) and 3230 specifies the PCI device ID of the
video card (also in hex, without "0x" prefix).
