[opensuse-buildservice] symlink control after build

Hi, sorry for not reading all that e-mails so maybe this was already spoken about. I did recently some simple script for controling dependencies and links in images used in SLEPOS. I found that there were some broken symlinks in that image. Interesting was, that these broken links also existed on SLES. So, what about adding some simple check for broken symlinks which cause at least warning? It can point to some problems with missing dependency or other error.. Best regards, Tomas Cech QA
