gnu-efi: ld.bfd: warning: /usr/lib64/crt0-efi-x86_64.o: missing .note.GNU-stack section implies executable stack

See also https://sourceforge.net/p/gnu-efi/bugs/28/. I noticed this during a local build of systemd against kinetic-proposed. It is caused by a warning added in a recent binutils (2.38.50.20220615-4ubuntu1 in kinetic-proposed).

Here's the relevant snippet from a systemd build:
