I'm just running a makefile target ">gmake check-TESTS".
The makefile makes a copy of ld-new (which is gold) and names the copy
ld, so gold is used to build ld1.

To be clear, I'm trying to convey that the first gold built by the old
ld linker doesn't segfault when executed.  I don't know how well it
works outside of that.

Editing ld1_LDFLAGS to add --no-ctors-in-init-array is effectively this.
Also the title of this post is "gold linker 2.22 REGRESSED for
DragonFly".  gold linker 2.21 doesn't need this switch to build itself.

I edited options.h to set ctors-in-init-array to false, followed by
">gmake clean" and ">gmake check-TESTS".

The result is better:
==================
All 2 tests passed
==================

Then I tried ">gmake check"
It got pretty far in the testsuite, complete through "split_i386.sh" and
starting failing at incremental-dump.cc due to numerous missing headers.
 I'm got a separate build directory, so the test might not be accounting
for that (e.g. source is in {top}/binutils-2.22 and my build directory
is {top}/build-b222).

Is that options.h generated or is ctors-in-init-array hardcoded to true?

Thanks for your help,
John
