Subject: [PATCH 1/2] pttc, lto: fix lto strnlen size warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Building with -flto results in

    .../pttc/src/util.c:48:15: error: ‘strnlen’ specified bound 4096 exceeds source size 1024 [-Werror=stringop-overread]
       48 |         len = strnlen(s, n);
          |               ^
    .../pttc/src/util.c: In function ‘yasm_advance_next_line.part.0’:
    .../pttc/src/yasm.c:790:14: note: source object declared here
      790 |         char s[1024];
          |              ^

Increase the size to fix this.
