I think this broken --enable-static-pie builds for some reason:

In file included from bench-timing-type.c:19:0:
bench-timing.h:19:0: error: "attribute_hidden" redefined [-Werror]
  #define attribute_hidden
In file included from <command-line>:0:0:
./../include/libc-symbols.h:361:0: note: this is the location of the 
previous definition
  # define attribute_hidden __attribute__ ((visibility ("hidden")))

Any suggestions how to fix this?  Just stick an #undef attribute_hidden 
in front of it?

Thanks,
Florian
