[PATCH,TARGET]FIX PR42457 AVR broken builds 4.5 regression

Subject: [PATCH,TARGET]FIX PR42457 AVR broken builds 4.5 regression

This patch fixes build for AVR when:

LTO is enabled - default as soon as libelf is present
ADA or other non-C/C++ language is built.

It moves C specific code to avr-c file, so that avr.c may compile without c front end.

OK for 4.5 head?
