ct-ng build hangs forever

[Claude <claude@cbcr.me>]

Hello,

I am trying to build the an x86 cross compile on a x86 Ubuntu 12.04 (up to
date wrt patches) host but ct-ng hands forever, with 1 core at 100%. I 
even let it run over night on 1 occasion but no success.

It hangs during compiling gmp. I turned on the debug option in ct-ng. 
Here is the output:

I tried different version of gmp. I also compiled it successfully standalone. 

I am not sure where to look now. Any pointer?
