GHS: Update the link line processing

-- add missing executable linker libs from:
   CMAKE_C_STANDARD_LIBRARIES
-- add missed transitive link libraries
-- add skipped library linker options
-- The linker expects -l../relative/path/to/lib.a to be relative to the top-level project
   Because there can be multiple top-level projects convert the path to an absolute path to target
