The plugin itself shouldn't need to know or care about that (remember, the
same plugin, built for a different host but the same target, should behave
identically). And to the extent the plugin cares about e.g. host C
library features, I think the expectation would be to use autoconf to
detect those.

I am suggesting that the logical concepts plugins should care about do not
include the host triplet at all. (They might include "how do I execute
compiled code", but I'd think that would best be externally configured in
some way.) Whatever the problem is, I don't think using a host triplet in
a plugin is the right solution.
But you, as a human being, wanting to know the configuration of a
particular distribution package, should indeed examine the metadata of
that package (or of your installation as a whole).
