predep_objects and postdep_objects are specifying the duplicate objects
which are better computed by gcc/g++ driver, since we want to generate
PIE, PIC and non-PIC combinations, let gcc decide on this, since it
knows best about linker options to use in each of these situations.
When we defer the linker options to driver, we also need to remove
-nostdlib from linker commandline options.
Remove duplicate directory creation for ${D}${bindir_crossscripts}/
This fixes a frequent problem we see during -fpie links e.g.
