Original patch from: gentoo/src/patchsets/glibc/2.9/3000_all_2.3.6-dl_execstack-PaX-support.patch
-= BEGIN original header =-
With latest versions of glibc, a lot of apps failed on a PaX enabled
system with:
cannot enable executable stack as shared object requires: Permission denied
This is due to PaX 'exec-protecting' the stack, and ld.so then trying
to make the stack executable due to some libraries not containing the
PT_GNU_STACK section. Bug #32960. <azarah@gentoo.org> (12 Nov 2003).
Patch also NPTL. Bug #116086. <kevquinn@gentoo.org> (20 Dec 2005).
-= END original header =-
