gnu-efi/0050-.S-add-non-executable-GNU-stack-marking-on-ELF-linux.patch
Richard Hughes 05aa603af3 Backport two patches from master to fix fwupd-efi 
Several x86-64 platforms all using AMI BIOS that reject the signed EFI binary
if we did not specify a 512 byte alignment.

It's certainly possible this is a bug in the AMI firmware.

See https://github.com/fwupd/fwupd-efi/pull/40

Subject: [PATCH 50/50] */*.S: add non-executable GNU stack marking on
ELF-linux
binutils-2.39 enabed a few warning by default
(https://sourceware.org/pipermail/binutils/2022-August/122246.html):
> The ELF linker will now generate a warning message if the stack is made executable.
Let's suppress the warnings in assembly files by adding non-executables
stack markings. This fixes at least systemd build which uses '-Wl,--fatal-warnings':
