No, I don't think it makes sense to add complexities to this test that
are 1. specific to Linux, and 2. hard to understand (why would anyone
have to understand what an "overflow gid" is, when maintaining a POSIX
test case?).
Instead, how about
a) if you just ignore the test failures — since you know you are
running them in a very special environment, or
b) we can mark these 3 tests as expected test failures if you
provide an identifier to mark them with, and a corresponding
condition, so that we can extend gnulib/modules/test-xfail.
