This commit removes system shared libs (e.g. libc, libdl, or libm) from
the prebuilt ELF check fix suggestion.
Bug: 141925662
Test: Write a bad Android.mk module and check fix suggestions

If we don't have any new dependencies, or we never set up the
check_elf_files.timestamp rule, don't create an empty one now.
There were >7000 of these unused and empty rules in my AOSP
aosp_cf_x86_phone build.
This was initially brought to my attention by the new checks in
https://github.com/google/kati/pull/189
Test: diff out/build-aosp_cf_x86_phone.ninja, only removed phony rules

This commit enables prebuilt ELF checks on ALL targets.
If this commit breaks your target, you may triage the breakage by adding
the following setting to your `BoardConfig.mk`:
BUILD_BROKEN_PREBUILT_ELF_FILES := true
And then fix the problem with the instructions:

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

This commit fixes prebuilt ELF checker for modules with
LOCAL_SDK_VERSIONS and depend on NDK shared libraries. This fix is
required because dynamic_binary.mk filters out NDK libraries thus those
libraries do not show up in DEPENDENCIES_ON_SHARED_LIBRARIES.
Bug: 119084334
Test: Create a prebuilt module with LOCAL_SDK_VERSION and check whether
the NDK libs in LOCAL_SHARED_LIBRARIES are passed to
check_elf_file.py.

This commit strips LOCAL_CHECK_ELF_FILES before comparing it with
`false` so that developers can add comments after LOCAL_CHECK_ELF_FILES.
For example:
LOCAL_CHECK_ELF_FILES := false # disable checks due to ...
Bug: 119084334
Test: Add some spaces after LOCAL_CHECK_ELF_FILES and run
CHECK_ELF_FILES=true make check-elf-files

This commit introduces a prebuilt ELF binaries checker. The checker
will check:
1. Whether all DT_NEEDED shared libraries are specified in
`shared_libs` (Android.bp) or `LOCAL_SHARED_LIBRARIES` (Android.mk).
2. Whether all undefined symbols in the prebuilt binary can be resolved
to defined symbols exported by its dependencies.
This ensures that prebuilt binaries won't silently become ABI
incompatible.
To check the prebuilt binaries, all of the dependencies must be
specified in `shared_libs` (Android.bp) or `LOCAL_SHARED_LIBRARIES`
(Android.mk).
If your prebuilt binaries cannot be checked for some reason, you may add
the following property to Android.bp:
check_elf_files: false,
Or, add the following setting to Android.mk:
LOCAL_CHECK_ELF_FILES := false
Bug: 119084334
Test: CHECK_ELF_FILES=true make check-elf-files
