Hi!

I get failure building ARM kernel. I can workaround it with. Are
system fdt headers used, or something like that?

I failed to copy the error message, but FDT_ERR_ALIGNMENT was
undefined symbol.

This is on 5.12-rc3.

BR,

I had another report on this. A 'git clean' solved it. I'm not sure
what the underlying problem is though. None of the auto builders have
complained either.
