Since the kernel has FPU emulation, we should not run into this crash even if
musl use the hard float instructions. That is also why the edgerouter BSP
can works previously. It seems a bug in musl.

We don't have an officially image type supported list for each BSP.
The core-image-minimal is only referred as an example in release note, but
that doesn't mean we only support this image type. A patch should not break
the build of an image type which is buildable currently at least.
