[yocto] Understanding "dev package contains non-symlink"

[Burton, Ross]

Hi Giordan,

https://wiki.yoctoproject.org/wiki/TipsAndTricks/Packaging_Prebuilt_Libraries
might be helpful to you.

One useful thing would be to show us exactly what files are being
installed (and what files are symlinks).  It sounds like xrootd is
messing up library installation...
