RISCV port for JDK11u

Hello,

Similarly to aarch64 port to jdk8u, if a backport to jdk11u is not going to
happen, we should explore having a long lived riscv-port-jdk8u repository.
It would make for a central place for the community to contribute, and for
other vendors to base their distributions on top of (Adoptium,
Debian/Ubuntu/any Linux distributions, and others).

Thanks,
Ludovic
