This makes it easier to use the docker container smoke test that
GitHub actions runs. There is also `make smoke-docker-race` that runs the
smoke test with `-race` enabled.
This makes GOARM more generic and does GOMIPS in a similar way to
support mips-softfloat. We also set `-ldflags "-s -w"` for
mips-softfloat to give the best chance of the binary working on these
small devices.
Add support for freebsd. You have to set `tun.dev` in your config. The second pass of this would be to remove the exec calls and use ioctl(2) and route(4) instead, but we can do that in a second PR.

This restores `make bin-windows` and also adds `make
build/nebula-windows-amd64.zip` to build the zip file.

This script will be triggered by any tag starting with `v[0-9]+.[0-9]+.[0-9]+` (i.e.
v1.1.0). It will create all of the .tar.gz files (or .zip for windows). The amd64 binaries will be
compiled on their target systems, the rest of the Linux architecures
will be cross compiled from the Linux amd64 host.
A SHASUM256.txt will also be generated and attached to the release.
Simplify the makefile by using implicit rules. The new structure for the
build directory when using `make all` or `make release` is:
build/$GOOS-$GOARCH-$GOARM/nebula
(The GOARM part is optional, and only used for linux-arm-6)
So, releases end up like `nebula-linux-amd64.tar.gz` or
`nebula-linux-arm-6.tar.gz`
This change also adds `-trimpath` to the build, to make the pathnames
more generic in our releases.
* Use golang.org/x/sys/unix for _linux.go sources
To support builds on GOARCH=386 and possibly elsewhere, it's necessary
to use the x/sys/unix package instead of the syscall package. This is
because the syscall package is frozen and does not support
SYS_GETSOCKNAME, SYS_RECVFROM, nor SYS_SENDTO for GOARCH=386.
This commit alone doesn't add support for 386 builds, just gets things
onto x/sys/unix so that it's possible.
The remaining uses of the syscall package relate to signals, which
cannot be switched to the x/sys/unix package at this time. Windows
support breaks, so they can either continue using the syscall package
(it's frozen, this is safe for Go 1.x at minimum), or something can be
written to just use both windows- and unix-compatible signals.
* Add linux-386, ppc64le targets to Makefile
Because 'linux' is linux-amd64 already, just add linux-386 and
linux-ppc64le targets to distinguish them. Would rename the linux
target but that might break existing uses.
