commit ed676313c55f70ca0f1f3e7cbd440980e231df3f

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.
