This is unrelated, it's a different file that is checked.

So it fails for:
$ /home/marxin/Programming/elfutils/src/elflint --gnu
/home/marxin/Programming/elfutils/tests/elfstrmerge
section [17] '.rodata': merge flag set but entry size is zero

$ readelf -SW /home/marxin/Programming/elfutils/tests/elfstrmerge | grep roda
  [17] .rodata           PROGBITS        0000000000402ea0 002ea0 0007bf 00 AMS 
0   0  8

As seen the section has SHF_STRING flag, thus having sh_entsize == 0 should be
fine.

@Mark: Can you please take a look?
