FreeBSD/ports ac80808 (r421068)Mk bsd.port.mk, Mk/Scripts qa.sh

Add a stage-qa check to check for the existence of SONAME in .so's.

If a port provides .so.X files, they have to have a SONAME for them to
work correctly.

While there, incorporate a reverse soname checks in proxydeps.
A port that needs a .so.X from another port which does not have a
SONAME.
