This ought to be unnecessary, given the $(sort ...) here:

> X509_CERTIFICATES-raw := $(sort $(foreach CERT,$(X509_CERTIFICATES-y), \
> $(or $(realpath $(CERT)),$(CERT))))

as that is supposed to remove duplicates.

However, I will admit there's a snag with my idea: $(realpath ...) doesn't
work if the argument path does not exist (hence the $(or ...)).
