requiring rpcgen.
[cross-compiling] (extra-libs): Likewise.
[cross-compiling] (extra-libs-others): Likewise.
[cross-compiling] (librpcsvc-routines): Likewise.
[cross-compiling] (librpcsvc-inhibit-o): Likewise.
[cross-compiling] (omit-deps): Likewise.
(sunrpc-CPPFLAGS): New variable.
(CPPFLAGS): Define using $(sunrpc-CPPFLAGS).
(BUILD_CPPFLAGS): Append $(sunrpc-CPPFLAGS).
(cross-rpcgen-objs): New variable.
(extra-objs): Append $(cross-rpcgen-objs).
($(cross-rpcgen-objs)): New rule.
($(objpfx)cross-rpcgen): Likewise.
(rpcgen-cmd): Define to use $(built-program-file). Expand
comment.
($(objpfx)rpcsvc/%.stmp): Depend on cross-rpcgen.
($(objpfx)x%.stmp): Likewise.
* sunrpc/proto.h [IS_IN_build] (_): Define.
[IS_IN_build] (_libc_intl_domainname): Likewise.
