I've applied, after doing one small change, see below.

I changed this to PPPD_DEPENDENCIES += instead of PPPD_DEPENDENCIES =.
Indeed, we're now in a conditional block, and we want to avoid
overwriting any PPPD_DEPENDENCIES assignment  that could have been done
before that. There is none in the current pppd.mk, but one could be
added in the future, so we really like to use += to add conditional
dependencies.

Thanks for your contribution!
