So apparently the problem on my development machine is that for some odd 
reason I don't have the "vgabios.bin" file, but I do have
the "vgabios-isavga.bin" file. According to my package manager (pacman), 
it is owned by the SeaBIOS package:

     usr/share/qemu/vgabios-isavga.bin is owned by extra/seabios 1.15.0-1

Other files in that directory are owned by the same package as well, for 
example:

     usr/share/qemu/vgabios-stdvga.bin is owned by extra/seabios 1.15.0-1
     usr/share/qemu/vgabios-virtio.bin is owned by extra/seabios 1.15.0-1
     usr/share/qemu/vgabios-vmware.bin is owned by extra/seabios 1.15.0-1

So I'm not sure what is the best approach here to fix this. It is 
definitely not a problem in QEMU because when I compile it from source I 
do get a "vgabios.bin" file in the build directory, but I do think that 
QEMU should try to use the "vgabios-isavga.bin" file when using the 
isa-vga device, so in some way we could fix it in QEMU, which also makes 
sense to ensure the filename is "vgabios-isavga.bin" for the isa-vga 
device and not plain "vgabios.bin", which really doesn't say much about 
the type of the graphics device.
