Mk/Scripts/qa.sh: Bogus 'xx doesn't have a SONAME' messages are printed by stage-qa for some shared libraries

Reason: 'grep -q SONAME' ends before it drains the pipe, pipe fails
when the remaining output is too long, and 'set -o pipefail'
causes the whole command to fail when it is supposed to succeed.

Remedy: Please apply the attached patch fix-SONAME.patch, or
alternatively remove 'set -o pipefail' from qa.sh
