I've never heard about nopreprpm10, but it is more important to say where
you build the package because debuginfo generator is tightly dependant on
the _setup_ in packages like 'rpm', 'redhat-rpm-config', etc.

Have a look at `rpm --eval %debug_package` output to see what happens
there, and to see why it is needed.  Then, study your system/user rpm macros.
On my system (Fedora 27 x86_64), there's is (in /usr/lib/rpm/redhat/macros):

  ...
  %install %{?_enable_debug_packages:%{?buildsubdir:%{debug_package}}}\
  %%install\
  %{nil}
  ...

. so the %debug_package content is automatically hooked right before
%install by default, but only if %_enable_debug_packages is defined (the
default though).  Then, you need to have all the stuff done correctly in
%__debug_install_post (namely /usr/lib/rpm/find-debuginfo.sh should be
%called) but this appears to be OK on your system.
