Re: RFA: AVR: Support building AVR Linux targets

Hi Joseph,
   C. Draw up another patch that restricts the AVR patterns in config.gcc to
-none and -elf.

A and C - I think both changes should be applied.

OK - the patch for item A is already applied. Here is a proposed patch for item C. I have not applied the patch as obvious because I was not sure whether it was better to accept avr-*-elf or avr-*-elf*. I went for the latter in case there were AVR ELF variants, but I defer to your superior knowledge.

OK to apply ?
