Subject: insane.bbclass: Detect if someone is not using our LDFLAGS

    We started passing --target-style=gnu/both to the linker. If the
    buildsystem is not picking up our LDFLAGS it will not have this
    hash in the binary. E.g. this is true for busybox. Add a check to
    insane.bbclass to check if we have a GNU_HASH in the elf binary.

    Make this a non fatal QA option until the majority of packages
    are fixed.
