So, if I understand correctly, it should be something like:

ifeq ($(BR2_PACKAGE_LIBCAP),y)
LTP_TESTSUITE_DEPENDENCIES += libcap attr
endif

And in the Config.in:

	select BR2_PACKAGE_ATTR if BR2_PACKAGE_LIBCAP

We would have two cases:

 * libcap not enabled, it uses cap_set_file() from the C library.
   Correct?

 * libcap is enabled, we add the dependency on attr so that libcap
   exposes cap_set_file().

Is this correct? Or is the dependency on libcap mandatory?

Thanks,

Thomas
