Change subject: util: Delete the build_cross_gcc utility.
......................................................................
util: Delete the build_cross_gcc utility.
Now that crosstool-ng can be used for any of the supported ISAs, the
build_cross_gcc tool is no longer needed.

- The entire process can be configured with a series of settings
- which are stored in a config file called {settings_file}. These
- settings can generally also be set from the command line, and at
run
- time using step 0 of the process. Many will set themselves to
- reasonable defaults if no value was loaded from a previous
- configuration or a saved settings file.''',

- When settings are listed, any setting which has a value which has
- failed validation or which hasn't been set and doesn't have a
- reasonable default will be marked with a X in the far left hand
- column. Settings will generally refuse to be set to invalid values,
- unless they were like that by default and the user refused to
correct
