[Bug middle-end/24295] New: [4.1 Regression] #pragma weak foo = bar no longer causes bar to be referenced

[rguenth at gcc dot gnu dot org]

Consider

static const double foo_local = 1.0;
#pragma weak foo = foo_local

with unit-at-a-time we get rid of the foo_local variable (because it is unused
apart form the weak decl).  This is a regression from 4.0 where we correctly
mark foo_local as referenced.

This breaks building Xorg.  rth fixed it for 4.0, somehow the bug came back.
