Building in a path containing spaces does not work

[kjellwinblad]

When trying to build this repository from a path containing spaces, it does not work.

How to reproduce:

mkdir "path with spaces"
git clone https://github.com/emqx/jq.git
cd jq
rebar3 compile

The problems with our makfile is fixed in #35 but the jq library still don't build with spaces in the path.

Unfortunately, this does not seems supper easy to fix as the problem might be due to inherent problems with automake build tools. See for example:

We should focus on the runtime issue first.

I think it's fair to set a hard rule to "we do not support spaces in build path"
