Error building i9515 kernel

My linux build machine died some days ago, and then I lost my working build environment.
Luckily I found this helpful post on XDA with a working VM out-of-the-box and then, after the usual repo sync… I found a strange error during kernel build

/bin/sh: -c: line 0: syntax error near unexpected token `('
/home/android/i9515/kernel/samsung/jf/scripts/Makefile.build:307: recipe for target 'scripts/mod/empty.o' failed

Changing the /bin/sh from /bin/dash to /bin/bash the error changes a little bit and shows some other infos

/bin/sh: -c: line 0: `set -e; echo ' CC scripts/mod/empty.o'; /home/android/i9515/kernel/samsung/jf/scripts/gcc-wrapper.py /home/android/i9515/prebuilts/misc/linux-x86/ccache/ccache /home/android/i9515/prebuilts/gcc/linux-x86/arm/arm-eabi-4.9/bin/arm-eabi-gcc -Wp,-MD,scripts/mod/.empty.o.d -nostdinc -isystem ccache: FATAL: /home/android/i9515/prebuilts/gcc/linux-x86/arm/arm-eabi-4.9/bin/arm-eabi-gcc: execv returned (No such file or directory)
[...]

So…this is simple an error with my cross compiler configuration. Google team changes the compiler name from arm-eabi to arm-linux-androideabi, and so it’s very simple to fix.
This is the diff for the “BoardConfigCommon.mk” file

Mission Accomplished

My first CyanogenMod new (little) feature is born. Today I’ve finished the “Development shortcut” project. It enables the wipe data and application force close option in the recent tasks list and in the notification area. These options will be available only if the Development mode is enabled.

The first version is only for Motorola defy mb525 and is available on my github repo. I do a pull request to Quarx2k in order to merge my mod in his “official” Motorola repo.

The next step is to merge it in the official CM dev branch and submit it to gerrit review. But the first CyanogenmMod 10.2 M build is coming (this weekend) with the code freeze phase. I have to be quick!
