Hello,
one of our developers reported that when we build libc in our environment
using Yocto Project we end up with corrupted debug symbols even though the
-g flag is passed to the CFLAGS variable. I noticed that in fact some gcc
commands (about ~300) are missing -g flag in the invocation. So now my
question is: is there some reason why some objects are built without CFLAGS?
You can get the list of objects without debug symbols (and CFLAGS) by
setting CFLAGS=" -g " for make and using grep for gcc or cross gcc in the
make execution log file and grep with an invert match for ' -g '.

I found some solution which I'm not sure if is correct. Simply apply the
patch from the attachment and run the build and there are 0 gcc invocations
without -g flag. With that patch in our environment I was able to get
functional libc debug symbols.

Looking forward to getting the answer on my questions and the review if my
patch is correct and should be applied in the glibc or if there is another
solution.

Best regards,
Tomasz Dziendzielski
