I’m not sure what you are saying here, but the situation with transforms is indeed confusing. 

The untransformed command ([*] in .work.log) has "-Wl,--version-script,babl.map”.  It would seem, then, that the appropriate BUILDLINK_TRANSFORM should transform that form of the command not something else that has already been transformed.

Does this mean that the argument splitting precedes the transformation in cwrappers?

Would the opposite order make more sense?

Are there some transforms that are best written in terms of the transformed arguments that make less sense for the pre-transformed arguments?

Should there be two types of transforms, pre- and post?

Cheers,
