From 0d8c114aa25cb093607feea5d98ce81d7389aa73 Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Tue, 28 Feb 2023 00:53:01 +0100 Subject: Makefile, seccomp.sh: Fix cross-builds, adjust syscalls list to compiler Debian cross-building automatic checks: http://crossqa.debian.net/src/passt currently fail because we don't use the right target architecture and compiler while building the system call lists and resolving their numbers in seccomp.sh. Pass ARCH and CC to seccomp.sh and use them.
