[avr-chat] Argh it happened again: compiler cannot create executables

[Rick Mann]

I'm re-building the AVR toolchain because I just got a new MacBook  
Pro. Building gcc 4.1 (I successfully built 4.0.x before), I'm  
getting this error again:

checking for C compiler default output file name... configure: error:  
C compiler cannot create executables


Can anyone suggest anything? I don't remember how I got past this  
last time. I've included config.log below. Thanks!
