Summary:                    CMAKE_SYSTEM_XXX variables should not be modified
when cross-compiling
Description: 
The file Modules/Platform/UnixPaths.cmake always appends /usr/local and other
paths to CMAKE_SYSTEM_PREFIX_PATH when on a Unix-like system, and likewise for
include and library paths.

This prevents setting up some cross-compiling scenarios which cannot be set-up
using the CMAKE_FIND_ROOT_PATH mechanism.

I think all CMAKE_SYSTEM_XXX variables defined in a Toolchain file should have
priority and not be modified.
Putting those variables in the cache does not work either, the variables can
still be modified.
