From 168cfe83b250d3166817549c1e96e6b1f02bcab4 Mon Sep 17 00:00:00 2001
From: Gerd Hoffmann <kraxel@redhat.com>
Date: Mon, 28 Aug 2023 13:27:09 +0200
Subject: [PATCH] CryptoPkg/CrtLib: add access/open/read/write/close syscalls
Needed by rhel downstream openssl patches, they use unix syscalls
for file access (instead of fopen + friends like the rest of the
code base). No actual file access is needed for edk2, so just
add stubs to make linking work.
