  Add the prototype of profil() to resolve below GCC error:

  cygmon-gmon.c: In function 'moncontrol':
  cygmon-gmon.c:349:7: error: implicit declaration of function 'profil' [-Wimplicit-function-declaration]
    349 |       profil((unsigned short *)(sbuf + sizeof(struct phdr)),
        |       ^~~~~~

Note that unistd.h in which profil() is normally present is not
sufficient here because newlib's unistd.h does not provide it.
