Add a testcase for i386 LD_AUDIT
This patch adds a testcase for i386 LD_AUDIT to check function return and parameters passed in registers. * sysdeps/i386/Makefile (tests)[elf]: Add tst-audit3. (modules-names): Add tst-auditmod3a tst-auditmod3b. ($(objpfx)tst-audit3): New rule. ($(objpfx)tst-audit3.out): Likewise. * sysdeps/i386/tst-audit3.c: New file. * sysdeps/i386/tst-audit3.h: Likewise. * sysdeps/i386/tst-auditmod3a.c: Likewise. * sysdeps/i386/tst-auditmod3b.c: Likewise.
