I just tried your suggestion. The problem is, that `-fPIC` is just need
during `do_install` since strangely that is when the plugins get
compiled.

        do_install () {
              oe_runmake 'DESTDIR=${D}' \
                         'PREFIX=${prefix}' \
                         'CONFDIR=${sysconfdir}/vdr' \
                         'VIDEODIR=/var/lib/vdr/video' \
                         'PLUGINLIBDIR=${PLUGINDIR}' \
                         'LOCDIR=${datadir}/locale' \
                         install
        }

Using `CXXFLAGS_append = " -fPIC` in `do_install` gives me this error.

        + do_install
        + CXXFLAGS_append += ' -fPIC'
        /srv/filme/oe/tangstrom-dev/work/armv7a-angstrom-linux-gnueabi/vdr-1.7.10-r3/temp/run.do_install.17984: line 540: CXXFLAGS_append: command not found
        ERROR: function do_install failed

Adding `-fPIC` to the global `CXXFLAGS` is not desired, since the main
binary should not be compiled with this flag.

What solution is recommended in such a situation besides patching the
Makefiles? Add 'CXXFLAGS+=${CXXFLAGS}' to `oe_runmake`?

Thanks,
