On debian distributions (Debian/Ubuntu), the GCC will enable the "-pie" flag by default. In this case, after this patch series "Introduce LTO build option"(1) had been merged, we will get following error: X86_64 xen platform error: /usr/bin/x86_64-linux-gnu-ld: -r and -pie may not be used together collect2: error: ld returned 1 exit status make: *** [_all] Error 2 arm64 kvm platform error: CC libkvmplat: shutdown.o CC libkvmplat: memory.o LD libkvmplat.ld.o /usr/bin/aarch64-linux-gnu-ld: -r and -pie may not be used together make: *** [/root/UF/unikraft/build/libkvmplat.ld.o] Error 1 So, we need to add "-no-pie" explicitly in CFLAGS to avoid such errors.
