The same problem exists on ia64 as well.  There are software packages that
explicitly compile with -Wa,--noexecstack, causing the same kind of mixing
stack notes with absense of notes (from the compiler-supplied object
files).  Instead of requiring to remember when --noexecstack should not be
used it is easier to make this case work as intented.
