I'm confused by this part. We warn that cross-compilation isn't yet supported if CrossBuild isn't set, but if it is set, we don't warn?

Rereading it again, I think that I should have left things as they are for the condition, but changed the warning message to be more explicit. It should say something along the lines of:
echo "Warning: compiling native components for a different OS is not yet supported"

Would you agree?

echo "Warning: cross compiling native components is not yet supported"
__buildnative=false

# Configure environment if we are doing a cross compile.

export CROSSCOMPILE=1

All of these references to Ubuntu and trusty... so is this support only valid on Ubuntu 14.*?

Yes (this file is identical to the same file in CoreCLR/RT).

If you request a cross build, should we display a warning and disable it if you're not on a supported system? e.g. what happens if someone tries to specify cross on OS X?

We have the same problem with CoreCLR and CoreRT.

Many of these aren't used in this repo, right? Can we remove them and only include the ones that are?

I'll do a cleanup when I'm back.
