What the other posters said, except that you shouldn't add "splitdebug" in
your make.conf. If you do that, it will affect all packages.
What you do instead is put this text into /etc/portage/env/sys-libs/glibc
(yes, it must be a text file, not a directory):
CFLAGS="${CFLAGS} -g"
CXXFLAGS="${CXXFLAGS} -g"
FEATURES="${FEATURES} splitdebug"
I'm fairly sure (I could be wrong) that splitdebug doesn't cause -g or
a derivative to be added to CFLAGS. Hence why I have "-ggdb" in my
CFLAGS.
That's why added "-g" above. Having it in CFLAGS by default slows down
compilation (with some packages dramatically, like webkit.) I only
enable it for splitdebug.
