Subject: [PATCH] getopt1.c: wrap the getopt_long and getopt_long_only
 functions around include directive

The header guard HAVE_GETOPT_LONG_ONLY can be used to check if the
functions are available or not, as the functions getopt_long and
getopt_long_only defined in getopt1.c uses the function _getopt_internal
which is glibc specific and cannot be used on other libc systems (for
example musl).
Hence we're wrapping those two functions with this include guard.
