ELFParseError for Atmel and NXP binaries

[s8maschi]

Description

I'm getting the following ElfParser error when opening these Atmel and NXP binaries in angr. I have not included all the files, just a sample set
problematic_binaries.zip

File "cle\backends\elf\elf.py", line 393, in get_symbol
    re_sym = symbol_table.get_symbol(symid)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "elftools\elf\sections.py", line 190, in get_symbol
    entry = struct_parse(
            ^^^^^^^^^^^^^
  File "elftools\common\utils.py", line 45, in struct_parse
    raise ELFParseError(str(e))
elftools.common.exceptions.ELFParseError: expected 4, found 0

This seems to be similar to #116 but i'm fairly certain the binaries are not corrupted in this case.

Most of them are from the P2IM unit test repository https://github.com/RiS3-Lab/p2im-unit_tests/tree/cdfd9bbc72e1cc87a1f5d3905804ae1f91539beb

The STM binaries from the same work without an issue.

Steps to reproduce the bug

I just load them into a regular angr project without any additional parameters

These binaries load for me and only show the traceback as a log message, so this isn't a showstopper, just a partial failure.

Moreover, readelf(1) is unable to parse the part of the binary that is generating these errors; I get a ton of Error: bad symbol index errors, which is the same thing being reported by angr. There's something wrong with the toolchain that's generating these binaries. Specifically, it looks like the .relocate section is marked with the ELF semantic tag for a relocation table, but it's not actually filled with valid ELF relocations.

If these binaries are meant to run on a platform that doesn't have relocations, you can just pass perform_relocations=False to the angr/cle constructor.
