fc-shell TCH DL handler: add support for CSD modes TCH DL capture mechanism in FC Tourmaline firmware has been extended to support CSD modes in addition to speech - add the necessary support on the host tools side. It needs to be noted that this mechanism in its present state does NOT provide the debug utility value that was sought: as we learned only after the code was implemented, TI's DSP has a misfeature in that the buffer we are reading (a_dd_0[]) is zeroed out when the IDS block is enabled, i.e., we are reading all zeros and not the real DL bits we were after. But since the code has already been written, we are keeping it - perhaps we can do some tests with IDS disabled.

# This script builds and installs binutils, gcc and newlib in the order
# necessary for the whole thing to work.  The present version is based
# on OsmocomBB's gnu-arm-build.2.sh script, which is in turn based on
# yet another source.  The present version has been concocted by
# Spacefalcon the Outlaw for use in the FreeCalypso project.
#
# This script needs to be invoked with two arguments:
#
# $1: the path to the directory containing the upstream binutils, gcc
#     and newlib source tarballs;
#
# $2: the path to the directory where the built toolchain should be
#     installed.
#
# Note that there isn't a single install step at the end, instead this
# script will build and install one component, then proceed to build the
# next component which depends on the previous one, etc.  For this reason
# you should create a dedicated install directory that is writable by your
# regular (non-root) uid, then run this script to populate that directory
# with the toolchain.
