update default OS for debugging on darwin

Not a big issue, but when debugging, I want a default that more closely matches my system, without having to give extra arguments when running cc1.

	* config/darwin.opt (mmacosx-version-min): Update default OS

Mike,
   Speaking of OS versions, can you take a look again at...

http://gcc.gnu.org/ml/gcc-patches/2010-08/msg01703.html

I think it is long past time to start moving the ancient darwin
releases into the unsupported target list. Again, that second hunk
removes  *-darwin1[0-9]* from the powerpc-*-darwin* case since
darwin10 was never released for powerpc.

But I run ppc on darwin10...  :-(  I would have to think about this, which if the patch is supposed to save me from from thinking about older system, is counter productive.  So, I'd propose I not think about this and we leave things as is.  We aren't saving much by adding a line to error out.

besides which, since we now have a compiler which is Darwin64  
compatible,
  perhaps the puredarwin folks might be interested in building for  
powerpc. (perhaps not ;-))
