Always check ELF files for `check-elf-files`

With this commit, the build system always checks ELF files when
`check-elf-files` is one of the make goals regardless
`PRODUCT_CHECK_ELF_FILES` is specified or not.

This commit also adds `BUILD_BROKEN_PREBUILT_ELF_FILES` for targets that
haven't been cleared.

If this commit breaks your target (usually breaks the targets running
`make checkbuild`), you may triage the breakage by adding the following
setting to your `BoardConfig.mk`:

    BUILD_BROKEN_PREBUILT_ELF_FILES := true

Bug: 141176116
Test: lunch aosp_crosshatch-userdebug && make check-elf-files

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For an outdated reference on Android.mk files, see build-system.html.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.
