Which is why we have them already trashed away as part of the generic
target-finalize step.:

    Makefile:
    741     rm -rf $(TARGET_DIR)/usr/include [...]

Before the patch, dtc takes 1.5s. After the patch, it takes 1.5s. I
haven't noticed any meaningful improvement.

The only interesting reason to go that route would have been something
along the lines of:

    DTC_INSTALL_GOAL = install-lib

    ifeq ($(BR2_PACKAGE_DTC_PROGRAMS),y)
    DTC_INSTALL_GOAL += install-bin
    [...]
    endif

But even then, I don't see the point (even since check-package does not
report the variable as being assigned twice, as it is in a conditional).

Regards,
Yann E. MORIN.
