They're not, obviously, and we do have an effective-target keyword for
this: init_priority.

The test is in gcc/configure.ac (gcc_AC_INITFINI_ARRAY), defined in
acinclude.m4. It requires not only target binutils, but also target
headers to work; however, you can override it with
--enable-initfini-array. You may have pass the same option when
configuring binutils at least on Solaris/SPARC (don't remember the
details offhand).
However, that wasn't the problem in the Solaris 11.4+ results I reported:
it *does* support constructor priority even with as/ld and the failures
have nothing to do with that issue. Here are the errors/warnings I'm
seeing:

+UNRESOLVED: gcc.dg/builtin-has-attribute.c compilation failed to produce
executable
The error about missing construcot priority support does occur, however,
on Solaris 10 up to 11.3 with ld, in addition to the ones above.
As for the test, it would be best to split it into two: one for the bulk
that doesn't need constructor priority support and can work everywhere,
and another smaller one for the rest, guarded by
dg-require-effective-target init_priority.
