 #@ This script creates the mips trusted SDK.
 #@ It must be run from the native_client directory.
 
 # This script is intended to build a mipsel-linux-gnu cross compilation
 # toolchain that runs on x86 linux and generates code for a little-endian,
 # hard-float, mips32 target.
 #
 # It expects the host machine to have relatively recent versions of GMP (4.2.0
 # or later), MPFR (2.4.2), and MPC (0.8.1) in order to build the GCC.
 #
 # Common way to get those is:
 # sudo apt-get install libmpfr-dev libmpc-dev libgmp3-dev
