24.1.50; paxctl: file temacs does not have a PT_PAX_FLAGS program header |

This is a fallout from bug #11398:
If the paxctl utility is present, but the system's toolchain doesn't
support the PT_PAX_FLAGS program header, then "paxctl -r temacs" will
fail:
test "no" = "yes" || \
test "X/sbin/paxctl" = X || /sbin/paxctl -r temacs
file temacs does not have a PT_PAX_FLAGS program header, try conversion
make[1]: *** [temacs] Error 1
make[1]: Leaving directory
`/var/build/portage/app-editors/emacs-24.1/work/emacs-24.1/src'
make: *** [src] Error 2
A patch is included below. I've tested it with binutils-2.22, both
with and without PT_PAX_FLAGS support.
