[Bug libc/397] New: getopt should not reorder argv

["nick at usenix dot org" <sourceware-bugzilla at sources dot redhat dot com>]

The function prototype for getopt  is

int getopt(int argc, char * const argv[], const char *optstring);

which says that argv is an array of const pointer to char. However, if PERMUTE
ordering is in effect, argv is altered (and is therefore abusing the "const"
requirement). The manual suggests that this function has a different prototype
than that in <getopt.h>, without the const. POSIX defines getopt with the const
(but forbids permute behavior). 

I think the only viable solution here is to remove the const ... as much as I
hate the idea.
