[Buildroot] [PATCH 1/1] package/vsomeip: add vsomeip to bildroot

Hello Maik,

Thanks for your contribution! Since it's your first contribution, I
obviously have a few comments, but it's nice to see contributions from
Continental! See below for my comments.

First of all, please don't "attach" patches, instead use the "git
send-email" tool to send your patches. This will ensure they are sent
the proper way, and can be applied.

Please add an entry in the DEVELOPERS file for this new package. This
allows us to know who is taking care of which package. This also allows
you to get notified when there are build issues with this package, or
get CC'ed when other people contribute patches touching this package.

Also, your package lacks a vsomeip.hash, which should contain the hash
of the tarball being downloaded, as well as the hash of the license
file (see other packages for examples).

No need to indicate Boost system, thread, log in the comment: these are
selected.

You forgot || !BR2_TOOLCHAIN_HAS_THREADS

Also, BR2_PACKAGE_BOOST has a dependency on BR2_USE_WCHAR, so it should
be replicated as well to your package.

According to https://spdx.org/licenses/, MPL is not a valid SPDX
license tag, it needs to have the license version. Looking at
https://github.com/GENIVI/vsomeip/blob/master/LICENSE, it's version
2.0, so:

VSOMEIP_LICENSE = MPL-2.0

Could you adjust your patch according to those comments, and send an
updated version ?

Thanks a lot!
