No.  But there are various architecture-specific aspects to optimization 
that may result in warnings showing up on only some architectures.

Florian has fixed this bug.

A check-compilers failure simply means that one of the tasks from the 
"compilers" run failed.

In general, if you did a "compilers" run when the build was broken, you 
will have an incomplete set of compilers that isn't good for testing 
subsequent glibc changes and will need to rerun "compilers" with the 
source trees in an unbroken state.

My bots using GCC release branches only rebuild "compilers" once a week.  
That means a short-lived glibc build breakage is likely to show up as a 
failure in "glibcs" rather than "compilers" (but if the build is broken at 
the wrong time, when "compilers" runs, the "glibcs" builds will be using 
the broken compilers for a week).

My bot using GCC master rebuilds the compilers every time (but only runs 
once a day, whereas the ones using GCC release branches will run more 
frequently if there are new glibc changes to test).
