Help with -dbg packages for a library

Dear Debian Mentors,

I have a specific question with regard to -dbg packages for
libraries. My understanding of generating -dbg libraries is like this:

1. We build the package with CFLAGS or CXXFLAGS = -g -O2 (for

2. We call dh_strip while exluding the dbg package, to ensure that
debugging sumbols are present there.

Now, my situation is that upstream generates special <pkg>_debug
packages by sending ./configure --enable-debug. While I achieve the
desired result with the CFLAGS mentioned above, upstream fears that
generating the library with debugging symbols first and then stripping
them may result in a slightly reduced performance (it's a numerical
computation library). While I am going to run some tests myself to
verify this, I just wanted to ask the mentors here about their
knowledge of this issue.
