[kvm-unit-tests PATCH 2/2] Link with "-z noexecstack" to avoid warning from newer versions of ld

Newer versions of ld (from binutils 2.40) complain on s390x and x86:

 ld: warning: s390x/cpu.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

We can silence these warnings by using "-z noexecstack" for linking
(which should not have any real influence on the kvm-unit-tests since
the information from the ELF header is not used here anyway, so it's
just cosmetics).
