Hey again,

Ok, I have tested now
* musl,
* eglibc 2.19, and
* uClibc 0.9.33.2

and with uClibc it builds fine!


However if using eglibc, building
src-plugins/generic/nl80211_listener/CMakeFiles/oonf_static_nl80211_list
ener.dir/nl80211_get_interface.c.o
fails (but with a different error then when using musl [see previous
mail]):

PS: I have logged the full build and can provide the log and .config
files if requested.
