elf: Use a temporary file to generate Makefile fragments [BZ #28550]
1. Use a temporary file to generate Makefile fragments for DSO sorting
tests and use -include on them.
2. Add Makefile fragments to postclean-generated so that a "make clean"
removes the autogenerated fragments and a subsequent "make" regenerates
them.
This partially fixes BZ #28550.
