Regenerate odm or vendor using combined sepolicy if --rebuild-sepolicy.

This allows merged devices to boot using a precompiled_sepolicy built
from merged sources, rather than recompiling this sepolicy at boot
time every boot.

Bug: 178727214
Test: Merge an R+S build using --rebuild-sepolicy and --vendor-otatools.
      Observe odm.img is rebuilt by the vendor otatools.zip
        when merging.
      Observe device boots using ODM's precompiled_sepolicy file.
Test: Same as above, for S+S.
Test: Merge an S+S build using --rebuild-sepolicy and *not*
        --vendor-otatools.
      Observe odm.img is rebuilt without using a separate otatools.zip.
      Observe device boots using ODM's precompiled_sepolicy file.

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
