Keep alphabetical ordering. This can be verified with:

    $ make check-package
    package/Config.in:182: Packages in: menu "Development tools",
                           are not alphabetically ordered;
                           correct order: '-', '_', digits, capitals, lowercase;
                           first incorrect package: libbacktrace

It is customary that we put the licenses after the source archives.

You should use the github helper macro, as this provides a better named
archive, and thus you do not need to set the _SOURCE variable either:

    LIBBACTRACE_SITE = $(call github,ianlancetaylor,libbacktrace,$(LIBBACKTRACE_VERSION))

> +LIBBACKTRACE_LICENSE = BSD

There are a lot of "BSD" license, so we want to have the exact one. The
closest would be BSD-3C, but the wording of the third bullet point is
slightly different, so it is not exactly BSD-3C.

I think we can list it as:

    LIBBACKTRACE_LICENSE = BSD-3C-like

Care to fix those and respin, please?

Yann E. MORIN.
