misc/cgo/testtls: static test fails

[aclements]

What version of Go are you using (go version)?

581a822 in the Go 1.20 development tree

What operating system and processor architecture are you using (go env)?

netbsd/arm, observed on the trybots for CL 448016 PS 2

What did you do?

I've been enabling dist tests for cgo on more architectures where it's not clear why they're disabled. One of the misc/cgo/testtls static build configurations crashes on netbsd/arm (but passes on netbsd/arm64). It's unfortunately not easy to extract tests from dist (something I'm hoping to improve), but I believe this is what the test is doing:

cd $GOROOT/misc/cgo/testtls
go test -short=true -count=1 -run= -ldflags=-linkmode=external -tags=static .

It appears all of the other misc/cgo tests pass once I skip that specific one.

What did you expect to see?

Test passes.

What did you see instead?

Test crashes with SIGABRT. See the trybot log.

I've seen a similar failure mode when running misc/cgo/testtls with static linking in our (Microsoft) Go fork CI pipeline. Could be related to #52141, where it was concluded that the failure was due to an old and buggy glibc version installed on the host.
