So what happens is:

At some point board code calls defaultenv_append() which calls
defaultenv_add_base() which in turn registers all default env snippets
including the one from CONFIG_DEFAULT_ENVIRONMENT_PATH. After this
defaultenv_append adds the snippet passed to it.
Instead you want CONFIG_DEFAULT_ENVIRONMENT_PATH to be the last instance
and register it right before using the default environment in
defaultenv_load().

I had some trouble understanding what was wrong and how you solved
it, the above is mainly for me. I hope I find it the next time I stumble
upon this ;)
Something tells me this is not the last time I think about this piece
of code.

Ok, applied.

Sascha
