# Sets the compiler environment variables to use a downloaded wheezy sysroot
# when building Dart with architecture ia32.
# Run this in the same working directory that you have run 
# sdk/tools/download_chromium_sysroot.sh in.
# Must be sourced, not run in a subshell, to modify the environment.
# Run with the command ". sdk/tools/set_ia32_sysroot.sh"
# Only tested and used on Ubuntu trusty linux. Used to build dart with
# no requirement for glibc greater than version 2.14.
