Well, since that is setting a value for CPUTYPE constant, it wouldn't
work to do two in a row, I don't think.  The last would override.
I don't know what would happen if you did something like:

   CPUTYPE=i586,i386

or something like that.   Probably depends on the code that is being built.

But, the documentation within /etc/defaults/make.conf say you are
best to not change the default value if in doubt.
