* Makefile.in (mips-tfile.o, mips-tdump.o): Depend on system.h.
        * mips-tdump.c: Include system.h, remove redundant headers.
        * mips-tfile.c: Likewise.  Convert all ctype function calls to
        macro versions defined in system.h.
        * objc/Make-lang.in (objc-act.o): Depend on system.h.
        * objc/objc-act.c: Include system.h, remove redundant headers.
