Adding examples of how to solve specific problems would be welcome in 
the documentation. This is a difficult area to document because every 
package has some subtle differences.

Optional settings for a package are fine however for things that are 
essential to building the package the config file should contain the 
needed set up. The --with-* and --without-* options are not validated 
and can be used to pass specific settings but I suggest you translate 
them rather than directly passing in settings. For example the RTEMS BSP 
builder uses `--with-rtems-bsp=bsp`, `--with-rtems-legacy-network`, etc. 
Again this depends on the package being built.
