I'd think dwarf2 would be downright easy in comparison.  All you want
is the comp_unit_die in dwarf2_build_psymtabs_hard.  read_partial_die
does not currently save DW_AT_comp_dir, the compilation directory, but
making it do so would be easy.

This will conflict with the patches I'm working on on the intercu
branch, but I can fix up the merge later - don't worry about it.
