From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>
Gcc 10 is much more picky about globals being defined in multiple objects
even if they are the same function. The functions fontHeight() and
stringWidth() are defined in a header file which places them in multiple
objects. They need to be static otherwise gcc 10 will not be able to build.
