Upstream llvm-readobj no longer accepts single dash prefix for long
options. Changed to double dash.
Also let the script to raise exception if rc is non-zero, to avoid
getting confusing error later in the program.

llvm-readobj has reordered some of its output, causing issues when
checking for DT_SONAME and other fields.

This commit updates how `check_elf_file.py` parses the symbol name
because the `llvm-readobj` (from clang-r353983) does not print "@" if
the symbol is not versioned.

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
