S/390: PR83420: Improve hotpatch option parsing.

With the attached patch we get rid of the following build failure:

/home/andreas/build/../gcc/gcc/config/s390/s390.c: In function ‘void
s390_option_override()’:
/home/andreas/build/../gcc/gcc/config/s390/s390.c:15361:16: error: ‘char*
strncpy(char*, const char*, size_t)’ specified bound 256 equals destination
size [-Werror=stringop-truncation]
strncpy (s, opt->arg, 256);
^~

--- Comment #1 from Andreas Krebbel  ---
The error messages I've posted were not complete. The important is that one:

/home/andreas/build/../gcc/gcc/config/s390/s390.c: In function ‘void
s390_option_override()’:
/home/andreas/build/../gcc/gcc/config/s390/s390.c:15361:16: error: ‘char*
strncpy(char*, const char*, size_t)’ specified bound 256 equals destination
size [-Werror=stringop-truncation]
strncpy (s, opt->arg, 256);
^~


And this should be easy to fix. Mine
