Apply the m68k optimisations also to the m68k Atari build (untested)
This build of OpenSSL will now require at least a 68020. It is my understanding that our CI builds a 68020-60 version of NetSurf so this should not be an issue.
These patches were originally written for FreeMiNT so have been previously tested on that platform.
