Moin moin,

This breaks the build on my machine (debian testing):
  OBJCLD   libvlccore.la
libtool: link: unable to infer tagged configuration
libtool:   error: specify a tag with '--tag'
make[3]: *** [Makefile:2436: libvlccore.la] Error 1

That's the usual "any non-C file will cause a non-C linker to be used" issue, I suppose you're in for creating a convenience library :)
I'm not sure why the buildbot is fine with this, but it's definitely using the obj-C linker instead of the C linker (https://jenkins.videolan.org/job/vlc-continuous/job/vlc-cont-debian-x86_64/lastSuccessfulBuild/consoleFull)
