Atomics support in Windows requires libwinpthread*.dll at runtime. One
way to get it is to install it with MinGW package, and copy alongside
the executable.
Update test Makefile targets for windows executables.
Allow running tests with Wine: `make WINE=wine CONFIG_WIN3=y
...`. That's useful when Wine binfmt support cannot be installed such
as on the CI hosts.
Add PPC64LE architecture and try to fix flaky multi-arch CI in gcc:

This switches the exec test to `SIGTERM` rather than `SIGQUIT` since the
latter didn’t seem to work in QEMU, and the distinction doesn’t really
matter for this test.
This also makes the `isatty()` check smarter by checking whether `STDIN`
is, in fact, a terminal.
Added qemu-alpine targets i386, arm32v6, arm32v7, arm64v8, s390x
