Problem discovered when enabling the 'minidlna' package, which has a dependency on 'libiconv-full' - a core LEDE package.

Compilation fails on 'libiconv-full' with undefined reference errors (linking errors) for objects 'aliases_lookup' and 'aliases2_lookup' in "libiconv.so":

Full build log is also attached

Tested with a full default configuration and only options enabled being GCC 7 and a modular option for the libiconv-full package, so that should rule out any external influence.

I did find one other reference to this issue on the LEDE forums a few months ago here: LEDE Forums: compilation fails on libiconv-full
