Carl-Daniel Hailfinger 0153293887 Not a single file is being rebuilt in v3 if build.h changes. That means
the console banner and the option table will never be updated with more
recent build.h strings.

Thanks to Mart Raudsepp for spotting this oddness.

x86emu doesn't care about the contents of build.h, it just uses build.h
to check whether it is compiled in conjunction with coreboot.
