[yocto] dnf fail in do_rootfs cannot find shared library

[Måns Zigher]

I have toke the rpm file that was produced. I found the file under the
build directory under
tmp/work/imx8mq-strix-linux/x_media/1.0-r44/deploy-rpms/imx8mq/temp/x_media-1.0-r44.imx8mq.rpm.
I used the following commands
7z x x_media-1.0-r44.imx8mq.rpm
7z x x_media-1.0-r44.imx8mq.cpio

The result from this gave me the file tree where I then could run
file usr/lib/libx_media_1.0.so

usr/lib/libx_media_1.0.so: ELF 64-bit LSB shared object, ARM aarch64,
version 1 (SYSV), dynamically linked, stripped

So I believe that I have concluded that the rpm include the file that dnf
is complaining about. I don't understand why dnf thinks that this
dependency is not meet when it clearly is part of the package. I have added
verbose flags to the dnf call but dose not give any more information.
I am not sure how I can proceed to find out what I have done wrong. The
recipe is a bit of a freak of nature because the binaries that I am
packaging is actually built using another toolchain but it is for the same
arch can dnf detect that?
