Your issue is indeed more a toolchain-issue than a cross compiling issue. Brad 
is the expert for that, but I think I should be able to help too...

Ok, we need more information...

This is what cmake 2.6 does when invoked initially:
$ cmake ..
-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done

How far did you get this working with your toolchain ?
