To support greenhill compilation, LDFLAGS removes the code that adds -T through addprefix to ARCHSCRIPT(greenhill requires a space between -T and ldscript files, but addprefix didn't do it). However,if we modified like this, when ARCHSCRIPT has more than one ldscript, the -T is only added to the first ldscript, but not to the following ldscripts, which results in a warning when linking.
To solve this problem, we can just add a space after $(SCRIPT_OPT) when using addprefix, instead of deleting addprefix.
