- cirrus: fix FreeBSD, guard against future breakage
- gdbstub: support socket debug for linux-user
- gdbstub: add multiarch tests
- gdbstub: fixes for m68k

* remotes/stsquad/tags/pull-testing-and-gdbstub-060520-1:
target/m68k: fix gdb for m68xxx
tests/tcg: add a multiarch linux-user gdb test
tests/guest-debug: use the unix socket for linux-user tests
gdbstub/linux-user: support debugging over a unix socket
gdbstub: eliminate gdbserver_fd global
