Bug 778730 - doxygen build fails

When a hyperlink splits across a page boundary it can come to the problem of "\pdfendlink ended up in different nesting level than \pdfstartlink".
To overcome this problem the \hyperlink is packed into a "\mbox" construct (as suffested e.g. in https://tex.stackexchange.com/questions/1522/pdfendlink-ended-up-in-different-nesting-level-than-pdfstartlink)
