[coreboot] Coreboot make script do not use custom, seabiosconfig file.

[Rostislav Okulov]

I made my own seabios config file (.seabiosconfig) and put it in root coreboot directory. Add it in configuration like this CONFIG_PAYLOAD_CONFIGFILE="~/coreboot/.seabiosconfig" Next I do ~/coreboot> make to build coreboot but .seabiosconfig file skipped by make script and default file used instead (/coreboot/payloads/external/SeaBIOS/seabios/.config)

How to properly add my custom seabios config file?
