e3: add patch to mark the stack as non-executable and disable tiny/crippled elf on 32 bit this way the stack can be marked as non-executable on it too http://www.gentoo.org/proj/en/hardened/gnu-stack.xml the 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 patch origin: http://pkgs.fedoraproject.org/cgit/e3.git/plain/e3-gnu-stack.patch
