Probably start with a note. The last option you gave is probably the
most suitable, to have RSB able to build the required dependency
packages from source. Whether to patch newlib or not should be
consulted to the newlib mailing list.

I don't know the ramifications to disable iconv, whether it is
actually needed for the builds being done or not.
