It is Linux x32 ABI. Compiler need supporting libraries and also
kernel. 
"
The x32 ABI was merged into the Linux kernel for the 3.4 release with
support being added to the GNU C Library in version 2.16.

Object file has specific format, too, so assemblers, linkers and
compilers have to support it.
Problem is that you have to recompile everything as x32 if you want
to link with something other than basic libs...
