	* iconv/Makefile [! elf]: Define CFLAGS-gconv_simple.c to
	-DSTATIC_GCONV.
	* iconv/skeleton.c: Include ELF header only of STATIC?GCONV is not
	defined.  Avoid using DL_CLL_FCT if it is not defined.

	* resolv/arpa/nameser.h: Include sys/types.h unconditionally.
	Include endian.h unconditionally.  Remove portability goop
	depending on #ifdef linux, #ifdef BSD, #ifdef machine-type.

	* sunrpc/rpc/types.h: Mark file so fixincludes won't modify it.
