I'm working on the assumption that people will grab binaries from
AdoptOpenJDK.

Does this mean the gcc version will change? If you have hard information 
on
this, I'd appreciate the URL.

If the minimum gcc version for 10 or 11 is above 4.8.5 across all 
platforms,
then I agree, but I don't have that information, so I figured I'd ask to 
cover all of the JDK versions, to be safe. 

Even if the gcc version does change, adding 4.8.5-specific code shouldn't 
break anything.

What do you think?
