Yes, trying to compile on arm the odroid c1 kernel, but even if the
uImage seems fine, it doesn't boot :

"Uncompressing Kernel Image ... LZO: uncompress or overwrite error -6 "

That's what I have when booting with the generated uImage-3.10.80,
while it boots fine with the uImage (coming from ubuntu, so something
we'll never ship, as we'll only build images with packages built on
the centos infra, and reproduceable, like I've done for the
raspberrypi2 kernels, built through mock in rpm format)


 file /boot/uImage-3.10.80
/boot/uImage-3.10.80: u-boot legacy uImage, Linux-3.10.80, Linux/ARM,
OS Kernel Image 5553029 bytes, Mon Nov 30 11:08:20 2015, Load Address:
0x00208000, Entry Point: 0x00208000, Header CRC: 0x17C04E9A, Data CRC:

file /boot/uImage
/boot/uImage: u-boot legacy uImage, Linux-3.10.66-49, Linux/ARM, OS

The file /boot/uImage-3.10.80 was built on the odroid c1, with the
following gcc/glibc :
gcc-4.8.5-4.el7.armv7hl
glibc-2.17-105.el7.armv7hl
