How to build ARM cross compiler using crosstool-ng

Crosstool-ng git commit version: 2ba44bb7619ad28238d29386da89989fedaff9a8
Environment: ubuntu precise x86_64


1. Download crosstool-ng

  git clone git://crosstool-ng.org/crosstool-ng

2. build crosstool-ng: see the $(CTNG_ROOT)/README
  #> ./bootstrap
  #> ./configure
  #> make 
  #> sudo make install         

3. build cross compiler with config included crosstool-ng
  #> ct-ng list-samples  ; you can see as followings or simliar after the command
