The AVR target has a flag EF_AVR_LINKRELAX_PREPARED that can be set in
the ELF header flags to indicate if a file is prepared for linker
relaxation or not.

The problem is that at th moment the flag is set unconditionally, in
every created elf.

In the first patch I propose making the flag conditional on whether
the assembler was passed the -mlink-relax flag or not.

In the second patch I update the linker to propagate the flag from the
input files to the output if a partial link is performed.

OK to apply?

Thanks,
Andrew
