[Buildroot] [PATCH v2 1/2] openjdk-bin: new package

From: Adam Duskett <Aduskett at gmail.com>

Paradoxically, building OpenJDK requires a pre-existing JDK.
This pre-existing JDK is called the "boot JDK."

The boot JDK for building JDK major version N should be a JDK of major
version N-1, so for building JDK11, JDK10 would be needed. This requirement is
an issue when building on most distributions, as the host JDK tends to be JDK8.

The AdoptOpenJDK project provides binaries that can act as the boot JDK to
build the target JDK, which is what this package provides.
