Explicitly include stddef.h when building the BTI tests so that we have a definition of NULL, with at least some toolchains this is not done implicitly by anything else:
test.c: In function ‘start’: test.c:214:25: error: ‘NULL’ undeclared (first use in this function) 214 | sigaction(SIGILL, &sa, NULL); | ^~~~ test.c:20:1: note: ‘NULL’ is defined in header ‘<stddef.h>’; did you forget to ‘#include <stddef.h>’?
