Sounds like a bug, please file a report.
I think this is a bug in objc.exp.  I think the initialization code  
and caching code isn't multiboard safe.

I see:

fgnu-runtime}'" check-objcmrs $ grep Exec testsuite/objc/objc.log

which seems right to me?  Be sure to include enough context to know  
what it is that you're seeing that is wrong.

Anyway, I see:

Native configuration is powerpc-apple-darwin9.0.0d1

so things are now working just fine for me.
