misleading error (real problem: unbound variable)

Error: build command failed

5: Docker Error: 404 Not Found

----------------------------

this error is a bit misleading the logfile shows the real problem:

/script: line 730: CONFIGURE_FLAGS[@]: unbound variable

This error can only be detected by executing the build script, not by butido itself.

A possible "fix" (although it isn't really a fix) would be to include build script output in the error trace.
