Following up to my own email. I can reproduce this with the following
cut down test case if I compile with '-O2 -fmerge-all-constants' on
MIPS.
extern const char *const _sys_siglist[128];
const char *const __new_sys_siglist[128] = { };
extern __typeof (_sys_siglist) __EI__sys_siglist __attribute__((alias (""
"__new_sys_siglist")));
extern __typeof (__new_sys_siglist) _new_sys_siglist __attribute__ ((alias
("__new_sys_siglist")));
