[Pkg-chromium-maint] Bug#799939: chromium: does not build / is not available for armhf

[Riku Voipio]

Hi,

With the following patch I got chromium for armhf built. This was with
arm64 machine in armhf chroot, so full 4G available. I assume for native
armhf 3/1 memsplit is needed.

Notice it needs a fix to objcopy/strip in binutils to handle stripping a > 2GB file.
I'm still working on cleaning up that patch.
