Todd Gamblin c8fb9b5479 bugfix: cc should not add -L or -Wl,-rpath in compile-only mode ... - Adding -L and -Wl,-rpath to compile-only command lines ("cc mode" or "-c") causes clang (if not also other compilers) to emit warnings that confuse configure systems. - Clang will print warnings about unused command-line arguments. - This fix ensures that -L and -Wl,-rpath are not added if the compile line is just building an object file with -c - This also cleans up the cc script in several places.		2018-08-08 01:51:51 -07:00
