No, for these files we aren't upstream and just periodically merge stuff
from there. So, you should try to discuss this in asan upstream and get
a fix committed there and we can then merge it and/or cherry-pick it.
Please see libsanitizer/README.gcc.
Also, it would be nice to understand what is different on your powerpc-linux
from everybody's else where it works, do you have too old or too new kernel
headers, something different?
