Hello,

I've been trying to build the toolchain using crosstool-ng for ARM
64bit as the target.
I'm using crosstool-ng 1.20.0

Also here is some info about the host I'm building it on:
ghatage@ubuntu:~/crosstool-ng-1.20.0$ uname -a
Linux ubuntu 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux

Here is what I've done so far:

> ct-ng menuconfig
> Select Target Options
>> Target Architecture
>>> Selected arm
>> Selected Bitness to 64 bit
> Selected C-library, set it to use glibc

So I'm building the toolchain which has glibc (instead of eglibc) for
target ARM 64bit

I checked the crosstool-ng website and the table where shows a '?' for
ARM 64 .. I'm guessing that it might be untested.. Is this the reason
why?
If so, has anyone had a successful build of the toolchain for ARM 64?
Any help / replies will be appreciated!

Regards,
Anup
