The problem can be reproduced with the following testcase:

$ cat auxv.c
#include <dlfcn.h>
#include <elf/common.h>
$ gcc -Ibinutils/include -W -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wshadow -Werror -c auxv.c

For the moment, I've removed the -Werror from ld/Makefile as a workaround.
The problem also occurs on Solaris 9, but Solaris 10 and 11 are fine.
