That also includes anything compiled and released as a program binary that must run on older Linux installations. Such programs have to be compiled with old copies of the system headers (and probably with an of gcc). While such programs themselves won't use AVX without checking for OS support, the glibc code on the installed system might. Such programs can be modified to run-time detect the required signal stack size - but cannot rely on glibc to convert SIGSTKSZ into a function call.
