Currently we provide a separate implementation of Stream_Attributes via s-stratt__xdr.adb which needs to be recompiled manually.
This change introduces instead a new binder switch to choose at bind
time which stream implementation to use and replaces s-stratt__xdr.adb
by a new unit System.Stream_Attributes.XDR.
Tested on x86_64-pc-linux-gnu, committed on trunk
