Work-around: changes the way bootstrap-lto.mk compares object files

The patch changes the way bootstrap-lto.mk compares object files during the
comparison of stage 2 and 3 by only comparing the disassembled code. It works
around situations where a possibly correct compiler can be produced while it
still has differences in their object files.

This also reverts the last patch, which was based on a false positive.
