kbuild: specifying phony targets?

kbuild: specifying phony targets?

[Timur Tabi]

I have a Makefile that works with 2.4 and 2.6 kernels.  On the 2.4 side, I have a rule 
like this:

all: mytext ${TARGET_DIR} ${TARGET_DIR}/ccil.o

mytext:
     @echo ${SOMETEXT}

This causes the text in variable SOMETEXT to be displayed right when the build starts.

How do I do the same thing with kbuild?  Is there a way I can get a kbuild makefile to run 
a phony target right at the beginning?

A phony target is not possible.
But use 'always' to tell kbuild what needs to be done.
Se also kbuild documentation: Documentation/kbuild/makefile.txt

I added these lines to my makefile:

always := syscall

syscall:
         @echo ${SYSCALL_METHOD}

and I got this error:

make[3]: *** No rule to make target 
`/root/AMSO1100/software/host/linux/sys/devccil/syscall', needed by `__build'.  Stop.

I need to specify a target that is NOT a file.  How can I tell kbuild that my target isn't 
a file, but just a rule that needs to be run?
