Recent versions of binutils dropped support for the a.out and COFF formats on sparc64 targets. Since the boot loader on sparc64 is supposed to be an a.out binary and the a.out header entries are rather simple to calculate in our case, we just write the header ourselves instead of relying on external tools to do that.
