[Olsr-dev] Need Help Fixing glibc openwrt compilation

[Nick]

I added the multiarch build environment tests for the openwrt-routing feed.
Testing now against multiple platforms I realized that olsrd is not 
building for arc_archs (builds with glibc instead of musl)

|Another person from the openwrt community already had a look at it, but 
was also not able fix the issue. Any ideas?

|It seems that arch linux already had similar issues:
