In fixing GCC PR driver/13577, I discovered both gas and ld silently
allow multiple -o options.

Is that a sin?  What is wrong with the last -o just overriding any
previous -o?

I found it a surprise. A quick straw poll of some other experienced
developers found it a surprise.  We did not think this situation
the same as -fsome-feature -fno-some-feature, which is flipping
the same switch on and then off.
