[Ecls-list] minor fixes for cross compilation

[Anton Vodonosov]

And one more minor note.

When you start (cross compiling) configure first time, information message says:

..
### 1) Vital information cannot be determined at configuration time
### because we are not able to run test programs. A file called
###		
### has been created, that you will have to fill out. Please do
..

I.e. build/cross_config file name is missed

Best regards,
