I believe there might be a misunderstanding here. You seem to think
Thomas suggested to remove ccache-stats because ccache-options now
allows to do the same.

But in fact, Thomas only suggested to change:

"""
ifeq ($(BR2_CCACHE),y)
ccache-stats:
	...
endif

ifeq ($(BR2_CCACHE),y)
ccache-options:
	...
endif
"""

by

"""
ifeq ($(BR2_CCACHE),y)
ccache-stats:
	...

ccache-options:
	...
endif
"""

i.e, ccache-stats continues to exist, the only difference with your
implementation is that it sits under the same ifeq ($(BR2_CCACHE),y)
condition. It's just a minor nit.

Best regards,

Thomas
