Details:
Building Octave with the '--without-fontconfig' option seems to work, but it
produces an Octave that can't do any plotting.
When I have more time I can go through historical versions of Octave to see
how they behaved, but in the current development branch, only a warning is
shown that says "features that depend on fontconfig will be disabled". Then
when attempting to plot anything, a runtime error is thrown:
warning: ft_text_renderer: unable to load appropriate font
warning: called from
axes at line 66 column 10
newplot at line 158 column 10
plot at line 222 column 9
warning: ft_text_renderer: unable to load appropriate font

This is with any toolkit.
Can someone more familiar with the plotting system help determine how this
should be addressed? Is fontconfig now a hard requirement for any plotting
function using any of the toolkits? For the OpenGL toolkits only? Should there
be a fallback path that allows gnuplot to be used without fontconfig support?
Or should all plotting be disabled?
