Not that I'm suggesting you didn't test your patch, but this line is
missing a backslash...

thanks for the catch. Actually, it has been tested ;)
It only breaks for folks that have a bbappend (it wasn't my case).

That definitely doesn't parse, without without a bbappend.

Patch to glibc is fine provided you resent it with proper SRC_URI change
and report on how it builds in OE with this change applied

we'll need a v2 to address the backslash, but also the patch itself.
It's currently incomplete, it misses the inclusion on other
architectures siginfo headers.

yes, I saw that but I thought its not causing any regressions so we
can accept it, however if you are working  on pan-arch solution then
we should wait.
