Toolchain broken on -CURRENT

Tue Jan 29 16:07:05 UTC 2019

Hi!

Please can I somehow to repair my -CURRENT installation? What happens:
I have a machine which I use to check current state of -current revision as a desktop.
It has a simple X11 desktop and I periodically update /usr/src with svnlite update and
rebuild world as in instruction.

At some moment (most likely I'm something do wrong), I have broken toolchain and
world does not compile anymore. With ld.lld segfault. How can I repaire my system 
without clean installation?

Thanks!
