Normally the installation process will supply the information required for the eCosConfiguration Tool to locate the host tools (cat, ls, etc.) necessary to perform a build.

Note: If the host tools are set here, they will take precedence over the host tools specified by the profile or PATH environment. This setting will also remain persistent across all profiles and on subsequent invocations of the Configuration Tool.
