It was caused by:
commit a87e1817a435dab6c6c042f9306497c9f13d4236
Author: Nick Clifton <ni...@redhat.com>
Date: Thu May 28 17:43:21 2020 +0100
Have the linker fail if any attempt to link in an executable is made.
PR 26047
* ldelf.c (ldelf_after_open): Fail if attempting to link one
executable into another. Ensure that the test is made for all
forms of linking.
Please open a binutils regression bug against 2.35.
