RH-Commit: [1/4] 04f6f83169f1c5545a0e2772b4babfc6a50bd5bf (thuth/qemu-kvm-cs9)
Recent versions of ld complain when linking the s390-ccw bios:
/usr/bin/ld: warning: start.o: missing .note.GNU-stack section implies
executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in
a future version of the linker
We can silence the warning by telling the linker to mark the stack
as not executable.
