FTR:

I think the primary motivation is to have cmake decide (or coerced)
into which host tooling is appropriate rather than have the packaging
coerce cmake (if the paths weren't arch specific cmake would have no
option but to use what is present). Former allows for more "smarts" to
be applied to allow controlled cross-compiling and moves the decision
what is compatible out of the packaging and into cmake.

At any rate, the ideal end result is to have frameworks install
everything related to development to architectured directories. So the
-devs ultimately become MA:same and can contain the build time tools
needed for their arch. At runtime cmake can then decide which of the
available tools to pick depending on the architecture it is building
on (or what the cmake toolchain file tells it to use).
