binutils 2.21.1 release?

[Alan Modra]

Is a 2.21.1 release planned soon?

How do you feel about the following collection of backports?  This
brings non-target parts of 2.21 reasonably up to date with current
mainline, with the exception of gold.  Some of the patches don't do
much (formatting, refactoring) but the idea behind applying them is
simply to make it easier to apply later mainline patches on 2.21.
I've mostly avoided target-specific patches because I figure it's up
to target maintainers to push them as they see necessary.

The bug fixes I really want to see in a 2.21.1 release are my fixes to
ld script expression handling.
