The concern here was just that we don't want the test to fail on
targets with weird integer sizes, so the list of targets was
restricted to just those where Ville had tested it.

But { target ilp32 lp64 } would surely be fine. The test will only
fail if a struct with two char-sized subobjects is the same size as
size_t. Feel free to change it to { target ilp32 lp64 }.
