The lazy DECL_RTL patch broke glibc builds on targets that use DWARF2.
This showed up as an ia64-linux glibc build failure.

A minimal testcase is:
extern __const char *__const _sys_siglist[64];
const char *const __new_sys_siglist[64];
extern __typeof (__new_sys_siglist) _sys_siglist __attribute__ ((weak, alias ("__new_sys_siglist")));

Compile this with -gdwarf-2 and we hit the abort at the start of make_decl_rtl.
The problem here is that attribute alias clears the DECL_EXTERNAL bit, so
we end up with a decl with none of DECL_EXTERNAL, DECL_REGISTER, or TREE_STATIC
set.  However, it is still not an auto.  I think the right fix is to add
another check for TREE_PUBLIC.

This patch has not been tested with a bootstrap yet, and has not been checked
in yet.
