In libc-common.bbclass, it set dependencies for the rpm packages. When
run 'rpm -qp --provides libc6-dbg-2.18-r2.0.x86_64.rpm', yes, it
provides 'eglibc-dbg  libc-dbg  glibc-dbg  libc6-dbg'.

But when bitbake parse the recipe and configure files, libc6-dbg is not
found and not package provides it. If you add one line such as:
IMAGE_INSTALL_append += "libc6-dbg"

bitbake complains:

ERROR: Nothing RPROVIDES 'libc6-dbg' (but
/mnt/sda8/poky-neil/meta/recipes-sato/images/core-image-sato.bb RDEPENDS
on or otherwise requires it)

Use glib-dbg does work. But if I use it in a recipe, when uclibc is
used, I have to edit the recipe.

So I update RPROVIDES_${PN}-dbg to let it provides libc6-dbg.
