I did that, and adding this to .rpmmacros does the deed:

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

I also had to place augment my rpmbuild definitions with an additional
'--define "_enable_debug_packages 1"'

I'm baffled how Amazon packages go about providing debuginfo, seeing as how
these facilities have been changed(?). I haven't investigated it.
