Bug#445595: libsmpeg0: libsmpeg-0.4.so.0.1.4 is falsely reported as needing an executable stack

[Russell Coker]

Package: libsmpeg0
Version: 0.4.5+cvs20030824-1.9
Severity: normal

"execstack -q /usr/lib/libsmpeg-0.4.so.0.1.4" reports that the shared object
requests an executable stack (via the 'X' in the output).

The below patch when applied to the source instructs the assembler that to
include a note that an executable stack is not needed.  This is required on
systems running SE Linux.
