Is v8 expected to support x32 ABI? I tried "make native" (using v8
bleeding_edge, r12652) on an x32 ABI Gentoo install, and it failed with
e.g.:

On the other hand, "make ia32.release" succeeded, but I'm not sure if
that's what should be done on x32.
For more info about this issue on Gentoo, see
https://bugs.gentoo.org/show_bug.cgi?id=423815
In case you wonder what x32 ABI is all about, please take a look at
http://en.wikipedia.org/wiki/X32_ABI and
https://sites.google.com/site/x32abi/
I have a working x32 install and can contribute patches, but any guidance
and feedback is welcome.
