[yocto] building SDK artifacts with external toolchain

[Belisko Marek]

Hi,

I have an dilema to solve. I have an SDK from vendor which contains
scripts to build u-boot + kernel + some kind of application and create
initramfs out of that and this can be flashed to NOR device and boot.
But setup and using is really horrible. Idea is to port this process
to yocto and have possibility to be used as yocto SDK for development.
Issue is that u-boot and kernel are obsolete (u-boot 2010 and kernel
3.18) and after few fixed I was able to buld and run u-boto with 7.3
arm ggc but when building kernel I got some issue with asm and I'm
kind of lost ;). So idea was to use toolchain which SDK provide but
it's again 4.9.4 (some linaro clone). Target is to use poky rocko with
this setup. I tried to build minimal image with external toolchain but
got some QA issues like:

gmp-6.1.2-r0 do_package_qa: QA Issue: libgmpxx rdepends on
external-linaro-toolchain-dbg [debug-deps]

[file-rdeps]

I can workaround those but to me it looks like it's somehow not
compatible or so (was using 4.9.4 linaro toolchain). My idea was to
maybe use older poky (when 4.9 toolchain was used) but I'm not sure I
like this approach. Other ideas? Thanks.
