GHS: Print status message regarding GHS_OS_DIR

-- Rename platform script so it runs before initial try_compile() in
   project() command.
-- Fix incorrect variable name GHS_OS_DIR_OPTION
-- Remove unnecessary ".*" from REGEX expression for GHS_CANDIDATE_OS_DIRS
-- Forward GHS_OS_DIR_OPTION to try_compile() and preserve trailing
   whitespace of the variable.
