[coreboot] Tinycurses depends on active video console.

[Mats Erik Andersson]

Hello all,

may I point out that the flags "-Wall -Werror" prevents tinycurses
to compile in case only a serial console has been configured, but
no video output. The culprit is an unused but defined variable "c".
The naive solution is to condition the creation of "c" by the flag
CONFIG_VIDEO_CONSOLE.
