If config.sub already converts them to m68k, so that m680[012]0 never 
appears in a canonical target name, then the code in config.gcc looking 
for m680[012]0 in canonical target names is already dead.  The proposed 
alias deprecations relate only to aliases appearing in canonical names, 
not those that config.sub handles (such as converting pentium-linux to 
i586-pc-linux-gnu).

If config.sub handles a target alias, config.gcc doesn't need to include 
it in the case statements, and testcases do not need to mention that 
alias.  Thus testcases don't need to know about the possibility of 
configuring for target pentium-linux.  If config.sub does not handle a 
target alias, testcases do need to know about it - and testcases checking 
for m68k-*-* fail to check for the other variant target aliases.

There are no test results recently posted for the m680[012]0 target 
aliases.
