Which distro and packages are used for testing?  I tried it with Ubuntu 
20.04 but the cross-compiler is named differently 
(powerpc64le-linux-gnu-gcc instead of powerpc64le-linux-gcc).

Sorry, I didn't understand the context behind the change request nor how 
the script is used.  I appreciate the effort behind the change and would 
like to help where I can.
