-# will delete the ld.so sym link prematurely and break the system. So we
-# will hard block and give manual migration instructions.
-# 2) Currently uclibc and uclibc-ng's iconv are in bad shape. We've been using
-# the breakout library. The disadvantage here is that we have to sprinkle
-# LDFAGS=-liconv on build systems that need to link against libiconv.
