When processing libraries on the command line, take into account any thusly named static archive (*.a) file and consider that for offloading. We will also scan the appropriate linker options passed in so we can determine if the library should be considered as whole-archive. The static libraries found on the command line will be 'sniffed' to determine if the static library is fat. This effectively negates the need to use -foffload-static-lib and -foffload-whole-static-lib which we should consider deprecated now. Add a deprecated diagnostic when -foffload-static-lib is used Refactor to bring along common code for the device check. Narrows the focus of what is considered to be processed from the linker only arguments. Pulls in objects from -Wl, instead of only archives, but is only part of a potential partial link step and is not fully processed. Signed-off-by: Michael D Toguchi <michael.d.toguchi@intel.com>

Make adjustments according to recent reviews, also add -rpath as an additional -Wl check, adding a test for that as well. Signed-off-by: Michael D Toguchi <michael.d.toguchi@intel.com>
