Chromium build fails with undefined references to libiconv at linking stage

[punishm...@gmail.com]

As per title, I have not been able to build the latest version of Chromium for two days now, the build always fails at the linking stage with errors about undefined references to libiconv

Reproducible by doing the following:

(1) Build the latest Chromium from source

(2) Build fails at the linking stage with an error about undefined references to libiconv

[51144/51144] LINK ./chrome
