+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.
