[Patch] m32 powerpc-darwin should default to fragile ObjC ABI.

[David Fang]

I noticed that the existing RUN test cases all kept x86_64-apple-darwin10 
even in the case of i386.  I can't claim to understand why, I merely 
(unintelligently) followed the pattern with minimal changes.
I rather liked the simple commands we tested offline yesterday:

e.g.:
clang -### -target powerpc-apple-darwin8 foo.m -o foo.o

as that was sufficient to see the difference in -fobjc-runtime=.
Feel free to amend/append the test as you see fit.
