commit ed676313c55f70ca0f1f3e7cbd440980e231df3f
Author: Martin Roth <martinroth at google.com>

    crossgcc/buildgcc: add parameter to show version number of tool
    
    By adding the version number of tools, we can help people keep up to
    date with their tool versions.  This will be used now to determine
    whether the IASL version being used is the version supported by
    coreboot.
