Is the goal for people to be able to build Emacs on Ubuntu 16.04, and run it 
under WSL? If so, that might be enough for now, and we wouldn't have to change 
Emacs.

I see my test program didn't output enough info, and had a typo. Could you 
please try the attached one instead? On Ubuntu 16.04.1 x86-64, this new program 
outputs:

personality (0xffffffff) returns 0x0, errno=0 (Success)
ADDR_NO_RANDOMIZE was clear
personality (pers0 | ADDR_NO_RANDOMIZE) returns 0x0, errno=0 (Success)
ADDR_NO_RANDOMIZE set successfully
personality (0xffffffff) returns 0x40000, errno=0 (Success)

and when run under GDB, it outputs:

personality (0xffffffff) returns 0x40000, errno=0 (Success)
ADDR_NO_RANDOMIZE was set
