It took me a while as things keep changing back and forth with CM10.2. Since CM10.2 has tons of bionic optimizations, I decided to leave cortex string optimizations for time being and added latest 4.8 toolchains for arm/linux and its own NDK. TWRP and jeroenqui’s kernel are included as usual.
Features
1. Replace stock kernel and recovery with @jeroenqui‘s MEOW-kernel and TWRP recovery. (Optional)
2. Replace Google toolchains for arm/linux with Linaro 4.8 ones from Mustaavalkosta’s github
3. Apply build configuration with Linaro suggested optimizations “-O3 -pipe -Wl,–hash-style=gnu -fno-tree-vectorize -fstrict-aliasing -Wstrict-aliasing=2 -Werror=strict-aliasing”
4. Fix codes breaking strict aliasing rules
5. Comes in form of automate shell script, the easiest Linaro build guide EVER
Requirements:
1. CM10.2 build environment – You can check on Build for yuga wiki for detailed instructions.
2. Oracle Java – Skip OpenJDK in wiki and install better ones from this link including adb and fastboot.
3. You need to install additional packages for compiling kernel. Type “sudo apt-get install lzop ccache” so that build kernel won’t break mid-way.
4. Make sure your default compiled ROM works without trouble as I got boot problems before and thought Linaro messed it.
Instructions:
1. Open terminal and go to your Android git repository.
2. Modify local manifests for jeroenqui’s kernel and TWRP by typing “gedit .repo/local_manifests/roomservice.xml” and hit enter. Added the following lines before ‘</manifest>’.
<project name="Mustaavalkosta/android_prebuilts_gcc_linux-x86_arm_arm-eabi-4.8.git" path="prebuilts/gcc/linux-x86/arm/arm-eabi-4.8" remote="github" revision="master"/> <project name="Mustaavalkosta/android_prebuilts_gcc_linux-x86_arm_arm-linux-androideabi-4.8.git" path="prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8" remote="github" revision="master"/> #Add this if you want to use MEOW-kernel (You can use others if you want at your own risk) <remove-project name="CyanogenMod/android_kernel_sony_apq8064" /> <project name="MEOW-kernel/android_kernel_sony_apq8064" path="kernel/sony/apq8064" remote="github" /> #Add this if you want to use TWRP <remove-project name="CyanogenMod/android_bootable_recovery" /> <project name="TeamWin/Team-Win-Recovery-Project.git" path="bootable/recovery" remote="github" revision="twrp2.7"/>
3. Download Linaro NDK package in tar.gz format and place in Android git repository
3. Make linaro patch script by typing “gedit linaro_patch.sh” and hit enter. Put contents inside with this ones and save then exit.

This will replace Google NDK with Linaro ones and patch build configuration and codes that break strict aliasing rules.
4. Make Linaro patch executable by typing “chmod a+x linaro_patch.sh” and enter.
5. Re-sync again by typing “repo sync” and enter. It will take a while for downloading new toolchains.
6. Apply Linaro patches by typing “./linaro_patch.sh” and enter. All should goes well but keep your eyes on each patch and see if there’s anything failed to cherry-pick or not. Fix those failed to cherry-pick yourself and move on.
7. Reload build configuration by typing “source build/envsetup.sh” and enter.
8. Your ROM is ready be cooked with Linaro now. Build it with whatever method you prefer and enjoy.
