AFAIK, installing gcc-multilib package will generate a symlink for
/usr/include/asm:
On my ubuntu box:
ls -ld /usr/include/asm
lrwxrwxrwx 1 root root 20 May 20 2019 /usr/include/asm -> x86_64-linux-gnu/asm
As another possible way: -I/usr/include/x86_64-linux-gnu manually.
clang -O2 -U __GNUC__ -I/usr/include/x86_64-linux-gnu
-I${RTE_SDK}/${RTE_TARGET}/include -target bpf -Wno-int-to-void-pointer-cast -c
t3.c
