    elf: Check for corrupt symbol version info

    The BFD linker with PR ld/23499 may generate shared libraries with
    corrupt symbol version info which leads to linker error when the
    corrupt shared library is used:

    /usr/bin/ld: bin/libKF5Service.so.5.49.0: _edata: invalid version 21 (max
0)
    /usr/bin/ld: bin/libKF5Service.so.5.49.0: error adding symbols: bad value

    Add check for corrupt symbol version info to objdump:

    00000000000af005 g    D  .data      0000000000000000  <corrupt>   _edata

    and readelf:

       728: 00000000000af005     0 NOTYPE  GLOBAL DEFAULT   25 _edata@<corrupt>
(5)
