Unfortunately no ... i already tried it, and it needs the real
file. Grrr ...

#    create  df/df.debug
/local/src/NetBSD/tool/bin/x86_64--netbsd-objcopy --only-keep-debug df 
df.debug.tmp
/local/src/NetBSD/tool/bin/x86_64--netbsd-objcopy --strip-debug  -R 
.gnu_debuglink --add-gnu-debuglink=df.debug df
/local/src/NetBSD/tool/bin/x86_64--netbsd-objcopy:st24479a: cannot fill debug
