[Buildroot] [git commit] libiio: Bump version to 0.7

commit: https://git.buildroot.net/buildroot/commit/?id=00deb6a7c11440766767cc07800661e8067df474
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The two previous patches have been merged upstream, so they have been
deleted here. Another patch (picked from upstream) has been added to fix
the build with thread-less toolchains.

Libiio v0.7 provides two new backends, a USB backend (using libusb-1.0)
and a serial backend (using libserialport).

Additionally, it is now possible to compile libiio with thread-less
toolchains. In that case, thread safety is disabled.
