How to elf/tst-ldconfig-* in cross test setup

[Vineet Gupta]

Hi,

The following tests fail invariably on ARC cross testing setup

FAIL: elf/tst-dlopen-self-container
FAIL: elf/tst-dlopen-tlsmodid-container
FAIL: elf/tst-ldconfig-bad-aux-cache
FAIL: elf/tst-ldconfig-ld_so_conf-update
FAIL: elf/tst-pldd

This is despite having ldconfig on target.

The issue is expected src-path for dso.

| [pid   168] renameat(AT_FDCWD, "/usr/lib/tst-ldconfig-ld-mod.so", AT_FDCWD,
|     "/tmp/tst-ldconfig/libldconfig-ld-mod.so") = -1 EXDEV
|      (Invalid cross-device link)

In cross setup, /usr/lib needs to be the host path where test is built or the dso
needs to be copied over to target at the canonical location. I'm not sure what the
right approach is so any pointers would be great.

Thx,
