I suspect this would have done the job:

$(obj)/font.o: $(srctree)/drivers/video/console/font_acorn_8x8.c
? ? ? ? $(cmd,cc_o_c)'
I prefer using $(call,shipped) and let kbuild figure out how
build an .o file from a .c file.

In other words - avoiding use of the internal to Makefile.build
variables in various places.
indeed, but I'd argue that 1) this would not be the first Makefile
using these internal macros (alpha and ia64 are using such construct
for aliasing) and 2) the `cmd_shipped' stuff is as internal than other
functions :-)
A quick grep in Documentation/kbuild will show that only the shipped
variant is documented.

We could implement a general copy command - this is needed in some places
like this.
