Re: Small change in NSObject.m ASM needed for PowerPC build

[David Chisnall]

Checking the ISA reference, it appears that the required atomic  
instructions appeared in the 486, so -march=486 should work.  I have  
an almost identical patch applied locally and it builds correctly with  
no modifications to the GNUmakefile, so I'm slightly confused as to  
why this fails for Fred.
