cpu/avr8_common: Fix link with binutils > 2.35.2
The xfa.ld script is incompatible with binutils > 2.35.2 and results
in firmwares that wont boot. Sadly, I couldn't figure out an elegant
way to fix the issue. Instead, I modified the linker script provided
by binutils to also include XFA.

cpu/avr8_common: move ldscripts from atmega_common
The ldscripts are already used for both ATmega and ATxmega, so it
makes sense to have them in the common folder.

4b2bcd560b makefiles/arch/avr8: Add xmega linker conditions
The current script doesn't allow change script path and name.
Add LDSCRIPT_COMPAT_PATH and LDSCRIPT_COMPAT_NAME default
values to allow a unique path inside atxmega folder.

699248c65f makefiles/arch/atmega.inc.mk: Rename to avr8.inc.mk
Atmel AVR-8 CPU was reworked to accomodate variants like ATxmega.
This rename to atmega.inc.mk to avr8.inc.mk to be compliant with
new directory structure.
