From 1c19bf8cc294e95c8de314cc457bcea6854c3a2d Mon Sep 17 00:00:00 2001
From: Alexey Neyman <stilor@att.net>

Subject: [PATCH 2/2] Macos does not have <elf.h> and needs a local copy

Also, move <elf/xtensa.h> up - generic <elf.h> does not have
definitions for xtensa relocations.

Local file, cygwin-elf.h, needs to include <stdint.h> for standard
integer types which is POSIX - rather than glibc-originated <features.h>.
