commit e7624d708d12c608daf179d90c0d6de74c24dd2c
Author: Stefan Liebler <stli@linux.ibm.com>
Date:   Thu Oct 4 13:07:29 2018 +0200

    Adjust name of ld.so in test-container.c.
    
    The test-container.c file assumes that ld.so is always named
    something like /elf/ld-linux-*.
    But e.g. on s390x it is named ld64.so.1 or ld.so.1 on s390.
    There are other architectures like power or mips with similar names.
    
    This patch introduces the new global variable support_objdir_elf_ldso
    which contains the absolute path to the runtime linker used by the
    testsuite, e.g. OBJDIR_PATH/elf/ld-linux-x86-64.so.2.
    The check in test-container.c is now comparing against this path.
    Without this patch, test-container.c is searching invalid files / directories
    and fails to find glibc/nss/tst-nss-test3.root/tst-nss-test3.script.
    Then the test tst-nss-test3 fails!

    ChangeLog:
    
    	* support/support.h (support_objdir_elf_ldso): New variable.
    	* support/support_paths.c (support_objdir_elf_ldso): Likewise.
    	* support/Makefile (CFLAGS-support_paths.c): Add definition
    	for OBJDIR_ELF_LDSO_PATH.
    	* support/test-container.c (main): Search for the ld.so
    	which is also used by the testsuite.
