merging BSDPort into jdk mainline

I understand that PowerPC support is no more on Apple goals and I'm
unsure about Oracle.
Project Zero is a very good approach to help PPC and ARM users get
recents OpenJDK on their machine.
That's why I asked about Zero with OpenJDK 7/8 on mainline.

There is many OSes around (Linux, BSD, Windows and OS/X) and many
processors (x86, x86_64, PPC, ARM) so a serious matrix in some cases
like Linux and BSD where all CPU archs are available. Zero is a
perfect fit for these OS and even if OpenJDK 7 or 8 are not available
for PPC under macosx-port, why not having them with bsd-port ?

It's still unclear to me where is the glue between Hotspot, CPUs and
OS and how to build an OpenJDK for an OS/CPU replacing native assembly
support by Zero.
