Samba 4.10.4 - Error loading module nfs4acl_xattr due to dependent libraries

[L. van Belle]

What did you use as build paramaters? 
I had the same problem, about 1.5 years ago. 

Fix was this commit in debian. 
https://salsa.debian.org/samba-team/samba/commit/247316b0b2fb712c506c461459c
0138f212a9257 

And was nfs-common install prio to the build? So check which packages you
need as build depend. 

I noticed you mentioned yum.. I only do debian (and related) 
But this should give the hint to fix you build.
