Patches for read only memory segments and elf header frames, compliments of 
redhat and Gnu.

These provide -z relro to ld, and adds "GNU_RELRO" under "Program Headers:" 
from readelf -l output. These patches aren't necessary for anything, but 
making memory segments read only and relocateable would certainly make 
exploits more complicated to achieve.

>From what I understand, to use Pax soft mode, the toolchain will need PT_GNU 
patches as well. One each for gcc, glibc, and binutils.
