It's definitely abinutils bug.

Rewriting and tweaking C-source will not fix a binutils bug.

The simplistic source just shows that avr-gcc actually can generate code that
binutils linker relaxation will shred. For sure there are more realistic
examles out in the world, maybe even assembler or auto-generated by some tool.

BTW, avr-gcc may generate a function wil several RETs if it detects that an
expilogue is "simple". That's preferred over jumping around.
