3.0.0 executable stack in libgnutls

[Andreas Metzler]

Hello,

with 3.0.0 libgnutls' stack is marked executable:
----------------
address@hidden:~/SVN/gnutls28/trunk$ readelf -l /usr/lib/libgnutls.so.26.14.12 
| grep -E 'Type |GNU_STACK '
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  GNU_STACK      0x000000 0x00000000 0x00000000 0x00000 0x00000 RW  0x4
address@hidden:~/SVN/gnutls28/trunk$ readelf -l 
/tmp/GNUTLS/gnutls-3.0.0/debian/tmp/usr/lib/i386-linux-gnu/libgnutls.so.28.0.0 
| grep -E 'Type |GNU_STACK '
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  GNU_STACK      0x000000 0x00000000 0x00000000 0x00000 0x00000 RWE 0x4
----------------

Note the "E" in RWE. Afaict this is caused by
./lib/accelerated/intel/appro-aes-x86.o missing a GNU-stack section.

(SID)address@hidden:/tmp/GNUTLS/gnutls-3.0.0$ readelf -S \
     ./lib/accelerated/intel/appro-aes-x86.o | grep -i stack
(SID)address@hidden:/tmp/GNUTLS/gnutls-3.0.0$ readelf -S \
     ./lib/accelerated/intel/aes-x86.o | grep -i stack
  [21] .note.GNU-stack   PROGBITS        00000000 001f19 000000 00      0   0  1

The source assembly files in
/tmp/GNUTLS/gnutls-3.0.0/lib/accelerated/intel/asm/ all seem to be
missing the GNU-stack note.
