[yocto] Recursion error in do_package task, building libgcc_8.3

[Ekaterini Voulgari]

Hello,
I'm building a custom image (based on poky-tiny distro with newlib) and 
I get a symlink recursion error at strip_files. Ι've found 
this:https://lists.yoctoproject.org/pipermail/yocto/2019-June/045838.html 
of some relevance. I tried with:

    INHIBIT_SYSROOT_STRIP = "1"
    INHIBIT_PACKAGE_STRIP = "1"
    INSANE_SKIP_${PN} = "ldflags"
    INSANE_SKIP_${PN} = "already-stripped"

in local.conf in which case I only get the second error(do_package).

What causes that recursion and where do I start looking to fix it?
