[OE-core] [PATCH] Make static lib builds (DISABLE_STATIC) configurable from local.conf

[ryan woodsmall]

The idea is to build an as-close-to-stock-as-possible Poky (or another)
distro, but include support for static linking natively in the installed
OS. Some of the bits I build/ship, including standalone static cross and
native toolchains, target Poky as the stable reference source OS. The
poky-tiny definition with musl exists, but doesn't quite cover what I need,
and some externals are built outside of bitbake, the SDK and packaging
system, so static compilation limits required libraries and gives me some
confidence that I'll run on Poky.

It's not a big deal at all to do a custom Poky-based distro so I can head
down that path, but thought this might be useful. The default remains sane,
setting "--disable-static", but provides a knob to turn if the old feature
is needed. Apologies if I missed the point here!
