Adding "-O2" shouldn't be necessary since normally it's set already when
   building OpenSSH/OpenSSL. And AFAICS, "-mtune=" only defines a subset of
   what is defined via "-mcpu=". However, for both switches "supersparc" or
   "hypersparc" may be used depending on the particular CPU, but "-mv8"
   should do for all sun4m machines.


note that there is one sun4m machine that uses a v7 cpu :-)
