“-linkmode external” selects the system (binutils/GCC) linker.  The problem is
with the Go (internal) linker.

It happens if the Go linker is used to produce a dynamically linked executable.
 For example, this happens if a pure Go (no cgo) program indirectly calls
getaddrinfo or anything else that needs NSS.
