Re: [PATCH] Disable building with i386-*, -march=i386 or -mcpu=i386.

There is not necessarily anything to do right now.  But it's something
to consider when contemplating the details of compiler-based submachine
selection and when contemplating a sysdeps selection revamp.

The point you may be missing is that it is probably desireable to have
an arch vs tune distinction in our sysdeps selection.  It's every bit
as worthwhile there as it is in the compiler.


Thanks,
