This patch fixes an issue whereby the compilation of partial sources
(packages without bodies that require them) would not occur when said
sources were remote call interfaces. This is required because such
interfaces may have bodies that only exist on the server side or vice
versa
Tested on x86_64-pc-linux-gnu, committed on trunk

* lib-writ.adb, lib-writ.ads (Write_With_Lines): Add
documentation and an extra conditional check for RCI units so
that generated ali files will list the spec only instead of a
body when a body is not found.--- gcc/ada/lib-writ.adb
