Ok.  Here's the final patch.  In the meantime, I've found that the
callee_pop_aggregate_return attribute is used for Windows targets, so
I'm only removing the netware reference in extend.texi.

After this patch, the only netware references in-tree are from toplevel
configure.ac (still needed for the netware support in src), config.sub
(from upstream), and gcc/po/*.po for config/i386/netware.h.

Bootstrapped without regressions on i386-pc-solaris2.10 and
x86_64-unknown-linux-gnu.

Ok for mainline?
