y or n per optional driver (virtio-gpu, stdvga, e1000, rtl8139, native r8169, AC'97, AHCI, NVMe), all y except the native
r8169, overridable with make DRV_X=n. Only drivers nothing else calls can be optional; the registry #ifdefs them and the
Makefile leaves their objects out. Built with every one off (links, none of their symbols present), with r8169 on, and
by default.
