Summary:
It seems a bad idea to change the default in the middle of a release
branch due to possible changes in global ctor / dtor ordering between
.ctors and .init_array. With FreeBSD 11.0's release imminent lets change
the default now for FreeBSD 12 (the current development stream) and
later.
FreeBSD rtld has supported .init_array / .fini_array for many years. As
of Jan 1 2017 all supported FreeBSD releases and branches will have
support.
