[PATCH, committed] Cleanup warning/error buffer target selection in light of -Werror

[Bernhard Fischer]

Hi,

Fixing a mishap from the early days of PR21061 was lying around locally:
Irresponsible of -Werror, warnings still are to go straight to the
warning buffer -- diagnostics will TDRT anyway. So i'm (un)installing this
hunk that should not have been installed in the first place.

My initial (misguided) thought was that if -Werror, then warnings should
go straight to the error-buffer which is of course not the right thing
to do. Note that in effect the erroneous hunk corrected below did never
have a negative side-effect.

This erroneous hunk was thus reverted as r130990 to again read like it did
originally:
