rampayload: Add the linuxcheck payload The i386.c file uses standard 3f8 UART for some simple diagnostic prints, and the libpayload console otherwise. This payload was used to debug Linux as a rampayload and was very helpful for that work. Change-Id: I1cce5528780cd825fd91a88137fa70abd9f218e7 Signed-off-by: Ronald G.

Makefile.inc, payloads: Enable -Wvla Variable length arrays are dangerous, so let's make sure they don't sneak back into coreboot or any of the payloads.
