[meta-xilinx] core-image-minimal fails to compile libxml

[Greg Anders]

I'm new to the Yocto Project and was trying to build my first image for 
a ZCU102 using the meta-xilinx-bsp layer. I followed the instructions in 
the READMEs and added the appropriate layers to my bblayers.conf file; 
however, when I run `bitbake core-image-minimal` the build finishes with 
an ERROR when building libxml:

    aarch64-poky-linux-libtool:   error: 'libxml.lo' is not a valid libtool object
    Makefile:597: recipe for target 'libxml2mod.la' failed

I've not yet been able to find a solution online. Is there a known 
solution to this issue?

NB: I am building this on Ubuntu 18.04.2 LTS.

Thanks,

Greg
