when building trunk GLIBC (seen with GCC @r221125; same source builds with GCC

c-reduce'd test case

A much shorter test:

const int __new_sys_siglist[] = {};

extern __typeof(__new_sys_siglist) _new_sys_siglist
    __attribute__((alias("__new_sys_siglist")));
extern __typeof(__new_sys_siglist) _sys_siglist
    __attribute__((alias("__new_sys_siglist")));

Suggested patch

Following patch skips all alias variables. This condition was part of my
initial version of patch:

https://gcc.gnu.org/ml/gcc-patches/2015-02/msg01753.html

I hope, as Honza rework the patch, this condition should be placed there.
