-This patch fixes a problem with -fsection-anchors and variables
-declared with "attribute ((alias ()))".  In some circumstances, both
-an alias (symbol equated to another symbol) and a normal definition
-(label plus space allocation) were being emitted.  See the PR for
-details.  This causes current glibc ld.so to fail on powerpc-linux
-where section anchors are enabled by default.
-
-The reduced testcatse from the PR looks like:
-
-extern char **_dl_argv __attribute__ ((section (".data.rel.ro")));
-extern char **_dl_argv_internal __attribute__ ((visibility ("hidden")))
-  __attribute__ ((section (".data.rel.ro")));
-
-char **_dl_argv __attribute__ ((section (".data.rel.ro"))) = ((void *)0);
-extern __typeof (_dl_argv) _dl_argv_internal
-  __attribute__ ((alias ("_dl_argv")));
-
-char* foo () { return _dl_argv_internal[0]; }
-
-The section attribute on _dl_argv_internal is one of the triggers
-for this bug.  I think glibc is doing something slightly dodgy in
-specifying a section on an aliased variable, but at least the section
-agrees with the real variable.

-Bootstrapped and regression tested powerpc-linux, all languages but
