 Update: The build of the package starts, but during compilation of
 dependent go14, the system hangs reproducibly:
 
 [...]
 regexp/syntax
 regexp
 go/token
 go/scanner
 go/ast
 go/parser
 os/exec
 os/signal
 net/url
 text/template/parse
 text/template
 go/doc
 go/build
 cmd/go
 <nothing happens beyond this point>
 
 and the system is frozen. Ping still works, but everything else hangs.
 
 Last output of top from another terminal:

 So apparently 5l makes the system crash, but only while linking cmd/go.
 
 This happens with NetBSD/evbarm on my RPI with 7.0.2, and also kernel 7.0.1
 and 7.0_STABLE from January 10th 2016.
