Subject: [PATCH v1 1/3] drm/ci: force use of BFD linker

When using a toolchain with gold as the default linker in Debian, the
kernel build fails:

x86_64-linux-gnu-ld: unknown linker
scripts/Kconfig.include:56: Sorry, this linker is not supported.

So force the use of the BFD linker. This was already part of the build
script but has now been moved to a separate script so that other jobs
(dtbs check, kunit) can use it.
