[PATCH] Fix tst-libc_dlvsym{, -static} on ARC: don't check _sys_{err, sig}list

[Vineet Gupta]

These symbols were recently deprecated but the test still checks for
them which fails for ARC.

Tested with arc-linux-gnuhf

-FAIL: elf/tst-libc_dlvsym
+PASS: elf/tst-libc_dlvsym
-FAIL: elf/tst-libc_dlvsym-static
+PASS: elf/tst-libc_dlvsym-static

|
| $ cat elf/tst-libc_dlvsym-static.out
| error: tst-libc_dlvsym.h:103: symbol _sys_errlist not found at any version
|

caveats:
  1. This does reduce test-coverage for existing ports with older
     versions of glibc where these symbols are valid, but reckon
     it is not an issue since the symbol is being deprecated anyways

  2. IMHO, despite the ABI freeze it should be fine for 2.32 too since
     it doesn't modify glibc ABI/API in any way, only a test-header is.

Please use TEST_COMPAT, as in malloc/tst-mallocstate.c.
