Subject: [PATCH] Fix for NVIDIA 470.256.02 driver for GCC 15
conftest.sh invokes GCC on its own, without going through the usual
kernel Makefile that would add the proper CFLAGS (e.g. -std=gnu11).
This means that it builds with the default of GCC, which in GCC 15
has changed to -std=gnu23 which and has backwards incompatible changes
that the kernel does not support. Force it to -std=gnu17 instead.
