Update eglibc-package.inc to let eglibc-dbg provides libc6-dbg.
The use case is that when libc6-dbg is needded to be installed into
image, we don't need change glibc-dbg to uclibc-dbg in recipe when we
change to use package uclibc as default C library.

Isn't PKG_${PN}-dbg set to libc6-dbg anyway (by libc-common.bbclass)?
Can you explain the use case and justification for this change a bit
more clearly?

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.

Kai

Isn't that still true of "libc6-dbg"? Worse, it isn't even guaranteed
that the eglibc-debug package will be named libc6-dbg on all targets; it
would probably end up as libc6.1-dbg on alpha-linux or ia64-linux for
example. Encouraging people to hardcode "libc6" doesn't seem very
wholesome.

I think this is the way to deal the "RPROVIDES" and please ref to
libc6-dev in eglibc-package.inc:
RPROVIDES_${PN}-dev = "glibc-dev libc6-dev virtual-libc-dev"
Thanks,
Kai

I'm not quite sure I understand what you're saying here. But, a few
observations:
- the RPROVIDES that you mentioned is somewhat bogus since, as
previously mentioned, the autonamer is not guaranteed to come up with
"libc6" for eglibc on all platforms
- uclibc doesn't include eglibc-package.inc anyway so it won't be
affected by any RPROVIDES in that file
- adding that RPROVIDES for uclibc would be especially bogus since there
are no existing platforms where uclibc does get autonamed as "libc6"
So, I still don't really understand how adding this extra RPROVIDES does
much to help with uclibc compatibility.
