It is already before fabricateDefaultCommands, so I assume the problem
is now visible only with a linker script, correct?

The problem, if I understand it, is that we create a
ARMExidxSentinelSection and add it to an OutputSection, but not an
OutputSectionCommand. Is Script->synchronize() currently taking care of
this? If so, can you remove the code that does it in this commit?

Instead of moving the creation earlier, could you add it to a
OutputSectionCommand when it is created at its current position?

Cheers,
Rafael
