[PATCH v3 3/7] pc-bios/s390-ccw/Makefile: Use -z noexecstack to silence linker warning |

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.
