Until today the implementation of binutils for the AVR architecture did not
support 8-bit relocations. This means that constructs like counted strings:
.byte 2f-1f
1: .ascii "blah"
2:
were impossible, because GAS would tell me "illegal relocation size: 1". The
above example works fine on almost every other supported architecture.
The attached patch implements support for BFD_RELOC_8 relocation type in
binutils, and for the respective R_AVR_8 relocation type in avr-elf32. Both
relocations that are resolved at assembly time as well as link-time applied
relocations work.
Also attaching a simple testcase which should assemle fine with the patch
applied, and will emit two errors without the patch applied.
