Linux changed this behavior in 16e72e9b30986ee15f17fbb68189ca842c32af58
(v4.11). Previously, extra pages were always mapped RW. Now, those pages will
be executable if the segment specified PF_X. They still must be writeable.

* A segment with filesz == 0, memsz > 0 should be an anonymous only
mapping. We were failing to load such an ELF.
* Anonymous pages are always mapped RW, regardless of the segment
protections.
