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.

In the end this should not matter as the resulting binary is not loaded by an
elf loader so this should be fine
