mlibc: M4 support: robustify headers, add sys/signal.h. 

* include/errno.h (ERANGE): New define.
* include/stdarg.h (size_t): Undefine before typedef.
* include/stdint.h: Likewise.
* include/stdio.h: Likewise.
* include/stdlib.h: Likewise.
* include/sys/types.h: Likewise.
* include/string.h: Likewise.
  (ssize_t): Undefine before typedef.
