The address we pick in sparc64.ld is also 0x60000000, so doing a fixed map on top of that is guaranteed to blow up. Choosing 0x40000000 is exactly right for the max of code_gen_buffer_size set below. No need to ever use MAP_FIXED. While getting our desired address helps optimize the generated code, we won't fail if we don't get it.
