[oe] Some recipes from my work on HipHopVM

[Marcin Juszkiewicz]

Some time ago I started working on porting HipHopVM for AArch64
platform. My job was to identify and build all dependencies. Effect of
it is in this patchset.

I added them to meta-oe/recipes-support/ just to show them and get
suggestions where to move them. Some may be useful for people outside of
HHVM (which is 64bit only and (iirc) supports x86-64 now).

For most of them I will have updates during next months.
