Trying to port a program to nolibc triggered a few trivial errors that
are worth being addressed:
  - inttypes.h is missing, while being generally recommended over stdint.h
    for being more portable. Here we add it, which simply includes stdint.h.

  - sys/select.h is supposed to be where struct fd_set and FD_CLR() etc
    are defined. Till now it was still in types.h. Let's create the file
    and move these definitions there.

  - memchr() was still missing, thus a trivial one was added.

Finally the help message from "make help" reported an inaccurate
installation path, omitting the dependency on $OUTPUT. This was
fixed as well.

  tools/nolibc: fix misleading help message regarding installation path
  tools/nolibc: add the more portable inttypes.h
  tools/nolibc: move FD_* definitions to sys/select.h
  tools/nolibc: add missing memchr() to string.h
