I've seen this failure in my VMs running from an NFS-mounted $HOME.  The
details in my case are about security context:

Executing: /usr/sbin/prelink -vfNR -r 0x6400000
./libuprobeslibgcc-O3default-prelink-debug.so
prelink failed: /usr/sbin/prelink: Could not set security context for
./libuprobeslibgcc-O3default-prelink-debug.so: Operation not supported
FAIL: uprobeslibgcc-O3default-prelink-debug prelink
./libuprobeslibgcc-O3default-prelink-debug.so
... etc.
