    elf: Build tst-relr-mod[34]a.so with $(LDFLAGS-rpath-ORIGIN)
    
    When --enable-hardcoded-path-in-tests is used only with DT_RUNPATH,
    elf/tst-relr3 and elf/tst-relr4 failed to run.  Their dependency
    libraries, tst-relr-mod3a.so and tst-relr-mod4a.so, are failed to
    load since DT_RUNPATH on executable doesn't apply to them.  Build
    tst-relr-mod3a.so and tst-relr-mod4a.so with $(LDFLAGS-rpath-ORIGIN)
    to add DT_RUNPATH for their dependency libraries.
