Hi,

OpenVG depends on EGL (--enable-egl):
"configure: error: cannot enable OpenVG without EGL"

EGL depends on gallium support (--enable-gallium-egl):
"configure: error: cannot enable OpenVG without egl_gallium"

The EGL drm module depends on gbm:
"configure: error: EGL platform drm needs gbm"

gbm depends on udev:
"error: gbm needs udev"

This dependency chain is present in Config.in, should this also be present 
in the mesa3d.mk-sections mentioned above? Is

ifeq ($(BR2_PACKAGE_MESA3D_GBM),y)
MESA3D_DEPENDENCIES += udev

not enough?

Regards, Bernd
