It is strange that the linker failed but the root process actually went on and even started sending the binder.

[zhanghai]

Javadoc for Rootjava says:

Note: you may see complaints from dex2oat in logcat during development on 64-bit devices. This
 * happens because we patch LD_LIBRARY_PATH for 64-bit libraries, and dex2oat is a 32-bit
 * executable. When a release APK is installed however, dex2oat is called at install time and
 * the odex should be successfully generated, preventing this error from occurring when you
 * launch the Java code as root. When this error is logged, we are likely running in JIT mode,
 * which may be significantly slower.<br>

So this might not be the root cause.

IRemoteFileService.Stub.DESCRIPTOR has moved to IRemoteFileService.DESCRIPTOR and this become broken.
