Mike Hommey aab856a217 Bug 1242074 - Avoid going back and forth between FasterMake and RecursiveMake; r=gps
FasterMake needs some RecursiveMake install manifests to have been
processed before doing its work, so we can actually end up processing
them twice because of the going back and forth from FasterMake in the
hybrid build system.

Set the dependency at the RecursiveMake level when doing an hybrid
build.

# The traditional Mozilla build system relied on going through the entire
# build tree a number of times with different targets, and many of the
# things happening at each step required other things happening in previous
# steps without any documentation of those dependencies.
#
# This new build system tries to start afresh by establishing what files or
# operations are needed for the build, and applying the necessary rules to
# have those in place, relying on make dependencies to get them going.
#
# As of writing, only building non-compiled parts of Firefox is supported
# here (a few other things are also left out). This is a starting point, with
# the intent to grow this build system to make it more complete.
#
# This file contains rules and dependencies to get things working. The intent
# is for a Makefile to define some dependencies and variables, and include
# this file. What needs to be defined there, and ends up being generated by
# python/mozbuild/mozbuild/backend/fastermake.py is the following:
# - TOPSRCDIR/TOPOBJDIR, respectively the top source directory and the top
# object directory
# - PYTHON, the path to the python executable
# - ACDEFINES, which contains a set of -Dvar=name to be used during
# preprocessing
# - INSTALL_MANIFESTS, which defines the list of base directories handled
# by install manifests, see further below
#
# A convention used between this file and the Makefile including it is that
# global Make variables names are uppercase, while "local" Make variables
# applied to specific targets are lowercase.
# Targets to be triggered for a default build
default: $(addprefix install-,$(INSTALL_MANIFESTS))
