disallow modular BINFMT_ELF

modular BINFMT_ELF gives unresolved symbols in 2.4 .

modular BINFMT_ELF gives the following unresolved symbols in 2.6:

Since modular BINFMT_ELF is pretty pathological I'd suggest the following patch:

 config BINFMT_ELF

Interesting. this causes me to wonder if we should bother making BINFMT_ELF an option at all...

I strikes me as something that everyone is going to say yes to. If someone really doesn't want ELF then they are probably smart enough to change the Config script.

We have platforms uClinux for which ELF is not the preferred format so we should at least be able to compile it out.

Similarly on bi-arch supporting platforms, CONFIG_BINFMT_ELF controls 64-bit ELF support which one might want to disable and only use CONFIG_BINFMT_ELF32 (or other config option which controls 32-bit ELF support).

Many nommu targets don't support ELF binaries at all.

And in addition to my previous post there's probably peopel who want only 32bit elf support on 64bit arches like paris64 and sparc64.
