    util/genbuild_h: Add compiler version
    
    It’s useful to note the compiler used for a build, and output it in the
    banner. Linux and SeaBIOS do that for example.
    
    ```
    $ dmesg | grep gcc
    [    0.000000] Linux version 4.7.0-rc4-686-pae (debian-kernel at lists.debian.org) (gcc version 5.4.0 20160609 (Debian 5.4.0-4) ) #1 SMP Debian 4.7~rc4-1~exp1 (2016-06-20)
    $ sudo cbmem -c | grep gcc
    BUILD: gcc: (Debian 5.4.0-6) 5.4.0 20160609 binutils: (GNU Binutils for Debian) 2.26.1
    ```
    
    The version information for the two supported compilers look like below.
    
    ```
    $ gcc --version
    gcc (Debian 5.4.0-6) 5.4.0 20160609
    $ clang --version
    Ubuntu clang version 3.5-1ubuntu1 (trunk) (based on LLVM 3.5)
    Target: x86_64-pc-linux-gnu
    Thread model: posix
    ```
