I suspect you were off by one on the version numbers.  At one point, I
know that Diab only produced DWARF version 1 output. And current GDB
indeed does not support that.

It should be easy to tell; if the ELF file has .debug_info, it's
probably DWARF 2.  I don't remember the names typically used by DWARF
1, but I think it's just ".debug".
