openssl10: fix runtime errors with Thumb2 when using binutils 2.29

When compiling OpenSSL with binutils 2.29 for ARM with Thumb2 enabled
crashes and unexpected behavior occurs. E.g. connecting to a OpenSSH
server using the affected binary fails with:
  ssh_dispatch_run_fatal: Connection to 192.168.10.171 port 22: incorrect signature

Backport upstream bugfix:
https://github.com/openssl/openssl/issues/4659

+Subject: [PATCH] {aes-armv4|bsaes-armv7|sha256-armv4}.pl: make it work with
+ binutils-2.29
+
+It's not clear if it's a feature or bug, but binutils-2.29[.1]
+interprets 'adr' instruction with Thumb2 code reference differently,
+in a way that affects calculation of addresses of constants' tables.
