1. Provide ARMv6l binaries …

   ARM is a quite popular for small computing clusters, and an interesting
   pet project to try Nomad on.
   
   Unfortunately, the current ARM builds don't run on Raspberry Pi's 1,
   Zero or Zero W as it is compiled with some operations not available
   there.
   
   When executing the current binary, you receive this message:
   
   ```
   Illegal instruction (core dumped)
   ```
   
   The difference is caused by the version of the ARM instructions are
   available on each version of the Pi.
   
   | Version     | Compiler arch              |
   |-------------+----------------------------|
   | Pi v1, Zero | armel, floating point (v6) |
   | Pi v2, v3   | armhf, floating point (v7) |
   
   Fortunately, cross-compiling using Go is not so troublesome. It is possible to
   produce an executable using the non-hf version of `gcc`.
   
   This commit introduces a new `make` target for armel binaries. It renames the
   previous one so it is clear the difference between artifacts versions.
   
   A couple of extra compilation dependencies are needed on the build machine.
   
   Tested `armel` o a Pi Zero W 1.3 and Pi 3, which executes, but there are not yet
   any jobs running. The `armel` binary should work on all Raspberry Pi models,
   while the `armhf` only works on Pi 2/3 and it is optimized.
   
   Fixes hashicorp#2517
