I thought it's "obvious", but it might not be so. One immediate problem is that the filter is broken, because on arm64, os.uname().machine returns "aarch64", so we incorrectly filter out the arm syscalls (there is just one: arm_fadvise64_64). Of course we could fix the filter, but I think it's better to nuke it altogether. The filter on applies to 1 arm syscall and 5 s390 syscalls, and we have 500+ other syscalls, so this "optimization" doesn't really matter. OTOH, if we get the filter wrong, the result is bad. And also, the existence of the filter at all creates problems for cross-builds. I wanted to get rid of 'generate-syscall-list.py', but we need to generate a backslash in the output. https://github.com/mesonbuild/meson/issues/1564 makes this very very hard, since any attempt to put a backslash an inline argument results in the backslash being replaces by a forward slash, which doesn't quite have the same meaning. So let's use a standalone script until https://github.com/mesonbuild/meson/issues/1564 is resolved.
