Unfortunately we have many different ways of building with OBJDIRS.
Some of them add a prefix (MAKEOBJDIRPREFIX) while others add
objdirs inside the build dirs. The same way we need to have consistent
SRC directories (we map all source directories to /usr/src so that
DW_AT_name is the same no matter what NETBSDSRCDIR is) we also need
to map objdirs consistently (for example to /usr/obj for DW_AT_comp_dir).
You can look at the dwarf bits by doing readelf --debug-dump in
any .debug file.

This is not specific to any commit, it just general background
knowledge that paths embedded in binaries need to be "normalized".
