Compile tst-prelink.c without PIE [BZ #21815]
tst-prelink.c checks for conflict with GLOB_DAT relocation against stdio. On i386, there is no GLOB_DAT relocation against stdio with PIE. We should compile tst-prelink.c without PIE. [BZ #21815] * elf/Makefile (CFLAGS-tst-prelink.c): New. (LDFLAGS-tst-prelink): Likewise.
