make: *** [Makefile:75: base-redhat-8] Error 1

Start by running make splunk-redhat-8 and read the Dockerfile around line 36, along with the Makefile target base-redhat-8 and the referenced install.sh. Confirm the build failure is caused by the BusyBox download returning 404, and consider the issue done when the target builds successfully.
