By trying it myself I will only find out whether it works or not, not
whether it is _supposed_ to work or not.

As a matter of fact I have already tried it and found that it doesn't
work.  The question is, is this a bug in NetBSD that I should file
a PR about, or am I using the wrong method?

I tried this (" -V MKDEBUG=Yes release").  The build completed
successfully (including the boot floppies), I was able to install the
resulting release, and the /usr/libdata/debug directory was populated
with .debug files.  But how do I make gdb use them?  I tried

  gdb --symbols /usr/libdata/debug/bin/sh.debug /bin/sh

but gdb still said "no debugging symbols found".
