Bug#1013341: /usr/bin/ld.bfd: warning: /usr/lib/crt0-efi-x86_64.o: missing .note.GNU-stack section implies executable stack
Package: gnu-efi

Severity: serious

Hi,
since the latest update of binutils to 2.38.50.20220615,
the systemd source package fails to build:
```

I originally raised this at systemd upstream [1], but it was mentioned
there, that this might actually be a gnu-efi issue.
[1] also contains links to the relevant changes in binutils which now
trigger this warning.
Marking as RC, as it causes a FTBFS

Michael
