That is what I first proposed and it was rejected by a global maintainer.

That being:
    I ifndef'ed ELF_DYNAMIC_INTERPRETER in elf*-<cpu>.c, so that I could
    include elf*-<cpu>.c in elf*-<cpu>-foo.c.  elf*-<cpu>-foo.c would
    define ELF_DYNAMIC_INTERPRETER so that elf*-<cpu>.c's would not be
    used.

Isn't that what I am doing??
