Run tst-prelink test for GLOB_DAT reloc
Run tst-prelink test on targets with GLOB_DAT relocaton. * config.make.in (have-glob-dat-reloc): New. * configure.ac (libc_cv_has_glob_dat): New. Set to yes if target supports GLOB_DAT relocaton. AC_SUBST. * configure: Regenerated. * elf/Makefile (tests): Add tst-prelink. (tests-special): Add $(objpfx)tst-prelink-cmp.out. (tst-prelink-ENV): New. ($(objpfx)tst-prelink-conflict.out): Likewise. ($(objpfx)tst-prelink-cmp.out): Likewise. * sysdeps/x86/tst-prelink.c: Moved to ... * elf/tst-prelink.c: Here. * sysdeps/x86/tst-prelink.exp: Moved to ... * elf/tst-prelink.exp: Here. * sysdeps/x86/Makefile (tests): Don't add tst-prelink. (tst-prelink-ENV): Removed. ($(objpfx)tst-prelink-conflict.out): Likewise. ($(objpfx)tst-prelink-cmp.out): Likewise. (tests-special): Don't add $(objpfx)tst-prelink-cmp.out.
