[Buildroot] buildroot support for OrangePI PC

[Eelco Chaudron <echaudron@xiot.nl>]

Hi All,

I decided to give this a shot, but I already get stuck at doing the 
u-boot part...
Looks like some toolchain issue, so before I dig into it more let me see 
if some one here has ran into something similar.

This is my config:

BR2_armeb=y
BR2_cortex_a7=y
BR2_ARM_EABI=y
BR2_ARM_FPU_NEON_VFPV4=y
BR2_TARGET_UBOOT=y
BR2_TARGET_UBOOT_BOARDNAME="orangepi_pc"
BR2_TARGET_UBOOT_CUSTOM_GIT=y
BR2_TARGET_UBOOT_CUSTOM_REPO_URL="http://git.denx.de/u-boot.git"
BR2_TARGET_UBOOT_CUSTOM_REPO_VERSION="4832e17787acb29734d895751bc7a594908aecc6"
BR2_TARGET_UBOOT_SPL=y

It all goes wrong when linking u-boot. Here are some snippets from the 
output:
   LD      u-boot

Makefile:1193: recipe for target 'u-boot' failed
make[2]: *** [u-boot] Error 139

When I build the same u-boot version using the ubuntu provided 
"arm-linux-gnueabihf-" toolchain it works fine.
I'm using the following to build it;

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- orangepi_pc_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

Any ideas?
