unable to follow directions to install Crosstool-NG on OS X

At the step where we invoke CrossTool-NG to build the compiler, I am getting:

Attaching build.log and the .config I was using.

[andrewboie]

workaround:

modify /usr/local/lib/crosstool-ng-1.23.0/scripts/functions to change calls to "stat" to use "gstat" (2 places)

[andrewboie]

by the way the crosstool-ng package in Brew is out but totally broken for me. built from source instead.

[nashif]

run ct-ng oldconfig, this should resolve this. the tool can handle both bsd and gnu implementations of stat, the config was created on Linux and the configuration was gnu specific.

[andrewboie]

@nashif since the xtools configuration in Zephyr is primarily for OS X users, can we revise the config in our tree to have this done already so they can omit this step?
