Jeff,
Unfortunately, even with the "--enable-debug=yes", "make install" does not include the debugging symbols for neither libraries (xlators) nor binaries. I realized that the problem is with the "install" command that strips both binaries and libraries even when the flag "-s" is not set. At least this is the behavior in my Arch Linux setting.
I found a solution which is to define my own PKGBUILD file (to build arch linux installation packages), with "options=(debug !stripe)". Somehow the "!stripe" must be setting some environment variable to force the "install" command to not stripe things. After installing the generated package with "pacman -U" I have binaries and libraries with their own debugging symbols ;). In your case you might be able to do the same with the rpmbuild [1].
Thank you,
