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