[PATCH] remove deprecated aliases

[Dirk Mueller]

Hi, 

the patch below removes -m386,m486,mpentium,mpentiumpro. They have been 
deprecated for ages, and broken for several gcc releases. Its time to retire 
them. 

bootstrapped, regtested on i686-suse-linux with slightly older mainline with 
no new regressions. 

Ok?

Since this is user visible, can a note be added to the 4.3 Changes page?

Yes, but it took me some time to actually figure out how to do that :)

Done now.

Thanks,
