Building rclone on aarch64

[Dmitri Goutnik]

Hi,

You're probably running out of memory. I'm able to build lang/go-devel and 
most Go ports (those that do build on arm64) with an additional 2G swap.

But in case of net/rsync, adding swap won't help much because this port is 
currently broken on arm64 [1,2]. Support for freebsd/arm64 is not yet 
officially released by the Go Project (it will be, in go1.14 which is due in 
Feb 2020) and many apps still have older dependencies that do not build on 
freebsd/arm64.

Looking at the rclone build log, its vendor/golang.org/x/sys likely needs to 
be updated to at least 33540a1f6037 [3]. This can be done manually for one-off 
build, but the port will probably stay broken until upstream updates vendored 
dependencies. 

Cross-compilation will also work with go built from the master branch.
