It works here for me:

  $ ./configure --enable-local
  [--SNIP--]
  $ make
  [--SNIP--]
  $ ./ct-ng arm-bare_newlib_cortex_m3_nommu-eabi
  [--SNIP--]
  Now configured for "arm-bare_newlib_cortex_m3_nommu-eabi"
  $ grep 'CT_CONFIG_SHELL=' .config
  CT_CONFIG_SHELL="${bash}"
  $ grep bash paths.sh 
  export bash="/bin/bash"
  $ ./ct-ng build
  [INFO ]  Performing some trivial sanity checks

How do you use the sample? If you just copy the crosstool.config file from
the sample, as .config, it will not work, indeed.

To use a sample, you have to tell ct-ng to use that sample:
  $ ct-ng [sample-name]

That's because the samples are so-called defconfig files, which contain only
the non-default values from the config options. ct-ng does the needed things
to bring a defconfig into a complete .config, that it can then use.
