Bug#793320: /usr/lib/x86_64-linux-gnu/libwavpack.so.1.1.6: executable stack in libwavpack.so.1.1.6

Package: libwavpack1
Version: 4.75.0-1
Severity: important
File: /usr/lib/x86_64-linux-gnu/libwavpack.so.1.1.6


it seems that wavpack on x86_64 is shipped with an executable stack:

readelf -l /usr/lib/x86_64-linux-gnu/libwavpack.so.1.1.6 |grep -A1 GNU_STACK
  GNU_STACK      0x0000000000000000 0x0000000000000000 0x0000000000000000
                 0x0000000000000000 0x0000000000000000  RWE    10

That's usually a *very* bad idea, especially in a media library, where stack-based buffer overflows can be quite common.

Can you please disable it?
