[arm] Inhibit compiler warnings about an implied executable stackarmlinux
Some versions of the 32-bit ARM linker seem to treat the absence of a
.note.GNU-stack section as implying an executable stack, and will
print a warning that this is deprecated behaviour.
Silence the warning by adding a .note.GNU-stack section to each
assembly file and retaining the sections in the Linux linker script.
