ppc: exec stack fix

execstack shows ppc kexec has an executable stack,
this leaves it vulnerable to buffer overflows.

Fix it by adding ASFLAGS --noexecstack

Tested on PowerMac G4 Macmini:
Without the patch:
dave@darkstar:~/kexec-tools$ execstack build/sbin/kexec
X build/sbin/kexec

With the patch:
dave@darkstar:~/kexec-tools$ execstack build/sbin/kexec
- build/sbin/kexec
