I think this is an ABI error. Ubuntu 16.10 come with GCC 5.3 which is
not binary compatible. I'm not using Ubuntu, but on a GNU/Debian
machine I had a similar issue and just renaming the GNAT GPL 2015
linker could fix the issue.

$ sudo mv /usr/local/gnat_releases/gnat_2015/bin/../libexec/gcc/x86_64-
pc-linux-gnu/4.9.3/ld
/usr/local/gnat_releases/gnat_2015/bin/../libexec/gcc/x86_64-pc-linux-
gnu/4.9.3/ld-orig
