Problem with make CONF=

[Boaz Nahum]

Hi.

I'm sucessfuly building two configurations on windows (lambda/lambda)

make CONF=windows-x86-normal-server-release images
make CONF=windows-x86_64-normal-server-release images

But when I try to build them both:

$ make CONF= images
Building target 'images' in the following configurations (matching CONF=):
* windows-x86-normal-server-release
* windows-x86_64-normal-server-release
make: *** common/makefiles: Is a directory.  Stop.
make: *** No rule to make target `images'.  Stop.

The help says:

Useful make variables
.  make CONF=             # Build all configurations (note, assignment is
empty)

I also tried (found in README-builds.html):
  make all-conf  images

Is there other way to build all configurations ?

Thanks
Boaz
