Experimental Windows cross-compiled binary build

This commit consolidates the work that has been ongoing over the
last few weeks in producing the single-binary builds of LuaRocks
based on the new distribution model described in
https://github.com/luarocks/luarocks/wiki/Project:-LuaRocks-new-distribution-model

The single-binary build is in a good shape for Linux,
it's a work-in-progress for Windows (binaries do build,
but some work on the dependencies is still necessary),
and is untested in macOS.
