[jdk11u-dev] RFR: 8247818: GCC 10 warning stringop-overflow with symbol code

[Jonathan Dowland]

11u-dev is tricky to build with GCC 11 and newer. GCC 11 is the default version in current Debian stable (and likely derivatives e.g. Ubuntu, but I have not checked) as well as RHEL 9 (and derivatives, likewise unchecked), so I think it's worthwhile to improve that.

This particular patch addresses one of the obstacles (a warning from GCC 10 onwards). It doesn't apply clean, but cherry-pick conflicts were trivial to resolve. It was backported from 16 to 15 and 13 and seems worthwhile for 11u.
