    Compiling TI OpenCL and dependencies from source

In the following instructions, keep in mind that I'm using an
install prefix of ~/ti as a placeholder while I attempt to bring on
OpenCL by hand. That, and some other paths will be replaced with
Buildroot-specific install directories later on.
Install host binaries

C66x DSP compiler

wget http://software-dl.ti.com/codegen/esd/cgt_public_sw/C6000/8.2.2/ti_cgt_c6000_8.2.2_linux_installer_x86.bin
chmod +x ti_cgt_c6000_8.2.2_linux_installer_x86.bin
# NOTE: this will not terminate due to some bug in TI's installer.
# Run without --mode unattended' so you can see when it's safe to kill the process.
./ti_cgt_c6000_8.2.2_linux_installer_x86.bin --prefix ~/ti --mode unattended
XDCtools 3.50.07.20

wget http://downloads.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/rtsc/3_50_07_20/exports/xdccore/xdctools_3_50_07_20_core_linux.zip
unzip xdctools_3_50_07_20_core_linux.zip -d ~/ti

TI ARM-cortex compiler

wget http://software-dl.ti.com/codegen/esd/cgt_public_sw/TMS470/16.9.2.LTS/ti_cgt_tms470_16.9.2.LTS_linux_installer_x86.bin
chmod +x ti_cgt_tms470_16.9.2.LTS_linux_installer_x86.bin
./ti_cgt_tms470_16.9.2.LTS_linux_installer_x86.bin --prefix ~/ti --mode unattended
Build TI's LLVM fork (don't worry, it's old and builds pretty fast)

mkdir ti-llvm
cd ti-llvm
git clone --single-branch --branch release_36_ti --depth 1 git://git.ti.com/opencl/llvm.git
git clone --single-branch --branch release_36_ti --depth 1 git://git.ti.com/opencl/clang.git llvm/tools/clang
# Keep the j[obs] number low here or you'll incure the wrath of Linux's OOM killer
make -j4 -f llvm/Makefile.ti all.x86
make -j4 -f llvm/Makefile.ti all.arm
Build OpenCL

git clone git://git.ti.com/opencl/ti-opencl.git
cd ti-opencl
git checkout v01.01.17.01
