mark the stack as non-executable and disable tiny/crippled elf on 32 |
|
bit linux so that stack can be marked as non-executable on it too |

|
|
|
this change will slightly increase the size of the e3 binary. |
|
|
|
On 32bit x86 the size in bytes reported by stat(1) is: |
|
- with tiny/crippled elf header: 13283 |
|
- without tiny/crippled elf header: 16880 |
