Fix rpath-link flag for SunPro C++ 5.11 on Linux 

Commit 82c081ba (Fix rpath-link flag for SunPro C++ on Linux,
2009-07-13) taught CMake to pass '-rpath-link' because SunPro C++ 5.9
does not support '-Wl,'.  Now SunPro C++ 5.11 does not recognize the
option without using '-Wl,'.  Detect whether to use '-Wl,' based on the
output of "sunCC -flags".
