[dunfell,PATCHv2] libdrm: add libdrm-{nouveau,radeon,intel} to RPROVIDES

The libdrm-{nouveau,radeon,intel} are generated by libdrm recipe.
To use these libraries as a dependency in another component,
It should be explicitly added as RPROVIDES.

I'm sorry, but this still doesn't make much sense to me. RPROVIDES doesn't
help with build time dependency and if something has runtime dependency
explicitly on libdrm-nouveau, then using libdrm as suitable provider
doesn't seem right, what exactly is the usecase for this, isn't it just
hiding the issue somewhere else?

@Martin,
I don't know why you think I'm hiding something.
I will use this when installing the rpm package using the dnf tool on the target image such as qemu or raspberrypi.

For example,
There is component A.
It needs libdrm-{nouveau,radeon,intel} packages to work properly.
When this A component rpm package is installed using dnf tool on the actual target image,
the libdrm-{nouveau,radeon,intel} packages cannot install at once if the component A had a libdrm as rdepends.

However, If component A has libdrm-{nouveau,radeon,intel} as rdepends,
When these A component packages are installed using dnf, these packages can also be installed at the same time.

Because libdrm-{nouveau,radeon,intel} is not provided as RPROVIDES, these packages cannot be used as rdepends directly.

I don't think you're hiding something, I just don't understand this
use-case.

libdrm-nouveau rprovides libdrm-nouveau, any package with runtime
dependency dnf should be able to install and pull libdrm-nouveau package
(_not_ libdrm package) to satisfy that dependency.

Why doesn't this work for libdrm in your case? Do you have libdrm-nouveau
package created and nouveau packaged inside?

Cheers,
