If you configure IDE support as a module (CONFIG_IDE), you
will soon find that ide-std.o and ide-no.o are missing.
This is because arch/mips/lib/Makefile says:
obj-$(CONFIG_IDE) += ide-std.o ide-no.o
[...]
quoted
3) use some smart trick in Makefile so that we include those
two files only if CONFIG_IDE is 'y' or 'm'. (How?)
obj-$(CONFIG_IDE_MODULE)
This does not work. Apparently, CONFIG_IDE_MODULE is not created
for makefile part.

Indeed -- my fault. Variables such as $(CONFIG_IDE) are four-state and
for the module case they are simply set to "m". But then you can use
"ifeq ($(CONFIG_IDE),m)". Another approach is to invent an additional
variable automatically set to "y" whenever CONFIG_IDE is enabled.
