This is a follow-up to c245a54aab348642178129a9aad501b81a3089b4.

‘%current-system’ is already parameterized within ‘run-with-store’, the root
cause is that ‘mlet*’ bindings are evaluated before the parameterization.

* guix/scripts/size.scm (ensure-store-item): Add ‘system’ argument and pass it
to ‘package->derivation’.
(guix-size): Adjust accordingly.

Hey,

> -(define* (ensure-store-item spec-or-item)

When I have a look to the derivation that is computed in that procedure,
it looks like it has the expected system (the one passed as a cli
argument). Do you have any evidence of `guix size` doing the wrong thing
after c245a54aab?

Thanks,

Mathieu

Sorry for the confusion, c245a54aab did fix the issue, I should remove the
"follow-up" line in the commit message.

This patch is more of a style change:

Since system has been passed to ‘run-with-store’ and parameterized within it, we
only have to deal with the ‘mlet*’ bindings which are evaluated earlier.

For this specefic case, only ‘ensure-store-item’ used in ‘mlet*’ bindings needs
the system, so we can simply handle it there.  And I think parameterizing system
around ‘run-with-store’ again made the procedure less clear.

Thanks
