shouldn't this be in Constants.Profile (full name)

We have Constants.PROFILE_ANDROID, but that is only for android. The target triplet is created with Triplet(Constants.Profiles.ANDROID), based on three constants, so probably we could have all possible triplets names as constants?

@johanvos Your suggestion of doing Constants.Profile (full name) brings back this PR: #229, where TripletProfile was created precisely.

I guess this is a big refactoring that should be tackled in a follow-up PR?

For now, what if we just do:

using configuration.getHostTriplet() we get the Linux triplet, right, I'll change it

better to replace with the getArch() on the targetTriplet (e.g. when we support x86-64 emulator/devices)
