[PATCH 2/2] getopt.c: use fputs()/fputc() instead of fprintf() to, save code space

[Freddie Chopin <freddie_chopin at op dot pl>]

This is another approach aiming to reduce code and RAM usage of 
getopt(). Using fputs()/fputc() makes the function about 200 bytes 
bigger than when using f[i]printf() (on ARMv7-M, Cortex-M3), but now 
getopt() and family have zero dependency on heavy-weight formatting 
functions.
