Interesting... Looks like avr ld decides to complain about the (empty,
contains only externs) lib-exports.o. No sections in there, but since
the damn thing is not marked relaxable in ELF headers, ld assumes that
there has to be an unsuitable section somewhere...
No, wait - those new warnings are not new at all; they are just added to
the pile of similar ones from other built-in.o. Could you give me an
URL of full build log?
