Please note that the above approach has been deprecated since
portage-2.1.9.24, due to inclusion of package.env support:

http://bugs.gentoo.org/show_bug.cgi?id=44796

In order to accomplish the same thing with package.env, you'd put
something like "sys-libs/glibc debug.conf" in /etc/portage/package.env,
and then you put your FEATURES and CFLAGS variable settings in
/etc/portage/env/debug.conf (same format as make.conf). This is
documented in the portage man page.

Thanks a lot for the updated information, will migrate to new approach
as soon as possible :-)
