Following the #19 comment above, both nvidia-xxx and bbswitch compile as expected. But virtualbox (from oracle, as the ubuntu one is unistallable) fails:
- inserted "EXTRA_CFLAGS := -fno-pie -fno-stack-protector" into the many 'Makefile' from /usr/src/... and /var/lib/dkms/.... ; they are well saved
- but reinstalling virtualbox ends with a crash, and all the modified 'Makefile' are reverted to their original status.

I may have miss something somewhere i suppose.
