Subject: [PATCH] Add gnu-stack notes

In binutils-2.39, GNU ld has added a warning when linking objects that
don't have a .note.GNU-stack section.  Since we build with
"--fatal-warnings", this causes a failure:

ld: warning: cert.o: missing .note.GNU-stack section implies executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker

This patch adds those sections to all of the .S files, so that they will
be in the objects, as well as updating our gnu-efi tree the same way.
