Increase the default 32-bit build frame size warning limit to 1280 bytes
That was already the limit with KASAN enabled, and the 32-bit x86 build
ends up having a couple of drm cases that have stack frames _just_ over
1kB on my allmodconfig test. So the minimal fix for this build issue
for now is to just bump the limit and make it independent of KASAN.
[ Side note: XTENSA already used 1.5k and PARISC uses 2k, so 1280 is
still relatively conservative ]

Tell the compiler to warn at build time for stack frames larger than this.
