But when I selected chromium (indeed, it was the use_sysroot problem that previously made my builds fail, which is now fixed in your repo), I encountered a new problem:

I removed nss from my host system and issued a 'make chromium-dirclean

Also, could you upload your config to pastebin or github, and link to it?
