Add support for the tracing infastructure in coreboot.

The compiler is forced to emmit special functions on every
    entry/exit of the function. Add a compile time option
    to support it. Function entries will be printed in
    the console. The CONFIG_TRACE has more documentation.

Patch for userspace tools will follow.
