The canonical method would be to regard `tramp-remote-path' as
connection-local variable. I fear this doesn't work yet properly whith
`tramp-remote-path'; will check.

This shall work. But you must instruct Tramp to accept the settings in
your .profile. This is done by adding the symbol `tramp-own-remote-path'
to `tramp-remote-path', as explained in the manual.

I fear this case isn't handled/documented yet properly. Will check next
week (just now I'm occupied by other duties)

Isn't it possible to define this dependency in the Makefile?

Hmm, I don't understand this completely. Could you pls give me an
example, especially what you mean by loading modules. A kernel module?
