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).
