Re[2]: ld: Not enough room for program headers

I tried to change the script, but ld was using an internal script. When I made
it use one of the scripts in lib/ldscripts, I got other errors about bad MRI
in OUTPUT_FORMAT or something. Even when I extracted the script it was using
(using --verbose) it would still produce an error when reading it back unchanged.

The script from ld was exactly the same as the elf64alpha.x script.
