As Java is used quite a bit in the enterprise world, having the option to
build the LTS version of OpenJDK is quite convenient and also a requirement
for many companies wanting to use Java.
As such, there are three options:
1) Continue only to support the latest version of OpenJDK.
2) Downgrade our existing OpenJDK package from 14 to 11.
3) Add an option to support either OpenJDK 11 or 14.
OpenJDK 11 and 14 currently have:
- The same configure options.
- The same license files and hashes for those license files.
- The same dependencies.
- The same method to build and install.
As such, supporting both 11 and 14 is not only an easy option to add to
Buildroot, but also a nice feature for users who wish to use Java in an
embedded environment with a company that mandates the use of the LTS version.
To make it explicit that this choice really is about LTS vs. latest, and
not about 11 vs. 14, the options are really named with LTS and LATEST,
so that future defconfigs will not have to migrate when the versions
changes (e.g. we update from 14->15, or from 11 to the next LTS).

[yann.morin.1998@free.fr:
- keep latest as the default, for existing defconfigs
- rename options: drop numbers, use LTS and LATEST

Other changes:
- Add --with-stdc++lib=dynamic to openjdk.mk or else openjdk will fail to
build because it defaults to looking for a static libstdc++ library.

Because one package relies on the other, bump both at the same time.
Other changes:
- Drop --with-cpu-port=aarch64 option as it is no longer a valid option.
(See https://openjdk.java.net/jeps/340)
- Add xlib_libXrandr as a dependency.

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.
Currently, only a x86_64 host is supported, for two reasons:
1) A 32bit x86 binary distribution is not available from AdoptOpenJDK
2) We didn't had access to a host machine using an architecture other
than x86-64
The provided unpack200 has an invalid RPATH and relies on libzlib.
When host-libzlib runs the install step, the following error is
generated:
*** ERROR: package host-libzlib installs executables without proper RPATH:
*** $(HOST_DIR)/bin/unpack200
Because unpack200 is a deprecated tool, removing it after installation
is safe and fixes the issue.

- fix comments in the code
