    Get rid of .car.global_data warnings for GCC build
    
    The "used" attribute was added in commit 27cf2472 which caused these
    warnings to start appearing when using the standard coreboot GCC
    toolchain:
    
    {standard input}: Assembler messages:
    {standard input}:96: Warning: ignoring changed section type for .car.global_data
    {standard input}:96: Warning: ignoring changed section attributes for
    .car.global_data
    
    The # at the end of the section name causes the assembler to
    ignore everything following the name. I verified that the resulting
    binaries are the same with and without the #.
