[PATCH v2 0/2] target/i386: Make sure that vsyscall's tb->size != 0

[Ilya Leoshkevich]

This series for the s390-next tree fixes [1]. Patch 1 is the fix, patch
2 is the new test to avoid similar regressions in the future.

v1: https://lists.gnu.org/archive/html/qemu-devel/2021-05/msg03219.html
v1 -> v2: Fixed a problem with compiling the new test on centos7. `make
          docker-all-tests` does not spot any other issues with the
          updated patch (it does fail though: a number of iotests have
          problems, there is a build problem with musl, etc, but this
          all happens without the patch too).
