--- Comment #1 from Florian Weimer <fweimer at redhat dot com> ---
I'm not sure if this easy to fix, at least consistently across the code base. 
This GCC/Clang difference may also affect other function attributes (such as
the weak attribute).

glibc also assumes that asm function labels change built-ins (which explicitly
tested at configure time).  Clang does not implement that, either.
