Hi,

every couple of days I rebase to the head of the -current and this time
I encountered a problem during toolchain build related probably to the
recent compiler changes. As I am mainly interested in building kernel I
just switched to kernel-toolchain which worked fine for me, but anyway,
this looks like a wider problem. Maybe I am missing some transition
option - previous builds were fine - if so I would be happy to hear any
pointers to fix it locally.

Below is the error report.

Thank you,
Jakub Palider
