linux-mako fails to boot when built with gcc 4.8

[Ricardo Salveti]

Kernel doesn't boot when the kernel is built with gcc 4.8 (default at saucy).

Same tree works when built with 4.7.

To test:
* Flash latest raring/saucy touch image at mako
* Install/extract the kernel from the linux-mako package (saucy)
* Run: abootimg -u /dev/block/mmcblk0p6 -k <kernel>
* Reboot

To restore to a working kernel, just flash the boot.img file available at cdimage (http://cdimage.ubuntu.com/ubuntu-touch-preview/daily-preinstalled/current/raring-preinstalled-boot-armel+mako.img) with fastboot (sudo fastboot flash boot boot.img).

Kernel tested: UBUNTU: Ubuntu-3.4.0-1.4

[Ricardo Salveti (rsalveti)]

Kernel 3.4.0-1.6, which is built with gcc 4.7, works fine again.

[Dimitri John Ledkov (xnox)]

linaro, cynogenmod, asop - are not yet using gcc4.8 for android kernel builds, as they are known not to work.
the 4.7 toolchain will be kept in the archive whilst we still need to build these kernels.

We're unlikely to fix this.

Is the problem still present with 2014.08 releases of gcc-linaro 4.8 and 4.9?
