Motivation for this change
Enable Intel Software Guard eXtensions (SGX) on x86 when using Linux 5.11.0 or later. Also enable KVM guests to create SGX enclaves if running Linux 5.13.0 or later.
SGX is enabled by default in Ubuntu's 5.11 kernel:
# nix-shell -p curl dpkg --command 'curl -s "http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-5.11.0-16-generic_5.11.0-16.17_amd64.deb" | dpkg-deb --fsys-tarfile /dev/stdin | tar Ox --wildcards "./usr/src/*/.config" | grep "CONFIG_X86_SGX"' CONFIG_X86_SGX=yThings done
