  You may need to customize your target macro file, which will be in
config/mips/<somethinglikemips-elf>.h - grep through the config scripts for
mips-elf or mips-*-elf to find out which header is actually used.  Then take
a look at Using and porting GCC: Target Macros : Debugging info.


Macros for SDB and DWARF Output
-------------------------------

   Here are macros for SDB and DWARF output.

`SDB_DEBUGGING_INFO'
     Define this macro if GNU CC should produce COFF-style debugging
     output for SDB in response to the `-g' option.

`DWARF_DEBUGGING_INFO'
     Define this macro if GNU CC should produce dwarf format debugging
     output in response to the `-g' option.

`DWARF2_DEBUGGING_INFO'
     Define this macro if GNU CC should produce dwarf version 2 format
     debugging output in response to the `-g' option.

  It might be as simple as just adding the relevant enabling macro, or it 
might not - I'm afraid you'll just have to try it and see...
