Non-AMD64 builds timing out if script: does exit 0

WFM. Looks like smth else is hanging or Build delays for open source project - #26 by native-api

Try tracing like I did:

env:
  global:
    - "PS4='+(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]:+${FUNCNAME[0]}(): }'"
script:
  - set -x; <command>
 # you will see trace from both your commands and Travis machinery
  <...>
  - set +x    # once you no longer want to see trace
