Not sure the best way to reproduce this, but it was reported in another bug and
in a mail thread.

"It seems like __efistub__text = _text; loses the section relative property of
_text."

2.) A symbol assignment to symbol defined in a section description in a linker
script can lose the section information.

"The real problem is that we are not tracking
absoluteness correctly."

(since using an intermediate assignment loses the section relative property
when using ld.lld)
