make build is executed on the host (not in the container)

[stucki]

The make build command does not work if the host has no PHP installed. The reason for this is that the bin/build.sh script is executed on the host, not in the Docker container.

This is probably related to #139.

Really wondering if nobody noticed this before :-)

Hmm I realize now that this is intended. However, the problem remains that make build is executed on the host. Going to change the issue title, leaving the issue opened...

At least PHP is fixed with #143
