Right, libdrm should not be needed in your configuration.

It looks like the dependency is brought in by libloader (src/loader/).  It is
unnecessary for the configuration, but is no harm.  It is potentially useful
when egl_gallium can do accelerated rendering on fbdev.

--disable-dri disables DRI drivers.

I will leave the bug open as I might not be able to fix it anytime soon. 
Patches are welcomed.
