Bug 1543982 - Part 1: Avoid re-configuring from within Gradle. r=emilio The inline comment explains what is happening here. The issue is that client.mk is setting MOZ_OBJDIR (and autoconf.mk is setting CC/CXX and others) as part of `mach build`, which means that recursively invoking `mach build` sees a different environment, and that triggers reconfigure. In some situations we can avoid this by recognizing that the environment has changed and setting it back to what it was at the time of `mach build` before client.mk adjusts it.

#
#   The registry generates the hookPayload that appears in actions.json, and
#   contains data from the decision task as well as JSON-e code to combine that
#   with data supplied as part of the action spec.  When the hook is fired, the
#   hookPayload is rendered with JSON-e to produce a payload for the hook task
#   template.
#
#   The ci-admin code wraps the content of this file (.taskcluster.yml) with a
#   JSON-e $let statement that produces the context described below, and
#   installs that as the hook task template.
