build.llvm.linux

# This script uses the build script to create a llvm-based linux cross
# clang package.  Set TOPDIR and TARGET before running.  TOPDIR should be
# The directory where you want to build everything (it will contain subdirs
# for sources, objects, etc) and the only target supported at the moment
# is mips-mti-linux.
#
# You'll have to install the following packages in Ubuntu 14.04:
#
#     git flex bison make texinfo cmake ninja-build
#     swig libedit-dev libncurses5-dev groff tcl
