# the standard library for each CFG_TARGET, but we only want to generate one
# standard library package. As a result, for each entry in CFG_TARGET we need to
# pick a CFG_HOST to get the standard library from.
#
# In theory it doesn't actually matter what host we choose as it should be the
# case that all hosts produce the same set of libraries for a target (regardless
# of the host itself). Currently there is a bug in the compiler, however, which
# means this is not the case (see #29228 and #29235). To solve the first of
# those bugs, we prefer to select a standard library from the host it was
# generated from, allowing plugins to work in more situations.
