Fabrice, All,

Actually, I think that users that are stuck on using OpenJDK 11 are
those big enterprise players, who will also have stringent requirements
on their build environment, and are thus stuck with years old distro,
like those RHEL-7 that Matt is running on his autobuilder.

So, I think we should just limit the dependency on host gcc-4.9 to
OpenJDK 16.

Applied to master with that fixed, thanks.

Regards,
Yann E. MORIN.
