Thanks for the test case.  The elflint program is getting confused when it
tries to find the .dynamic section.  The PT_DYNAMIC segment is at address
0x32000.  It happens that the .tbss section is at sddress 0x32000.  Since the
.tbss section is SHT_NOBITS, it does not take up any address space.  The
.dynamic section then follows it, also at address 0x32000.  In the readelf -S

  [18] .tbss             NOBITS           0000000000032000  00032000
       0000000000000008  0000000000000000 WAT       0     0     4
  [19] .dynamic          DYNAMIC          0000000000032000  00032000
       0000000000000240  0000000000000010  WA       3     0     8

This is confusing elflint.  It is using gelf_offscn to return the section at
offset 0x32000.  That winds up being the .tbss section, not the .dynamic
section.  Based on that it decides that there are no DT_NEEDED entries, and
issues the .gnu.version_r warnings.

I don't see any gold problem here.
