Subject: [obv] Fix false argv0-symlink.exp FAIL running under a very long directory name

Hi,

checked in as obvious:

Starting program: /home/jkratoch/redhat/gdb-test-fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff/gdb/testsuite/gdb.base/argv0-symlink-filelink ^M
[...]
(gdb) print argv[0]^M
$1 = 0x7fffffffda39 "/home/jkratoch/redhat/gdb-test-", 'f' <repeats 169 times>...^M
(gdb) FAIL: gdb.base/argv0-symlink.exp: kept file symbolic link name

after "set print repeats 10000":

print argv[0]^M
$1 = 0x7fffffffda39 "/home/jkratoch/redhat/gdb-test-fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff"...^M
(gdb) FAIL: gdb.base/argv0-symlink.exp: kept file symbolic link name

after "set print elements 10000":

print argv[0]^M
$1 = 0x7fffffffda39 "/home/jkratoch/redhat/gdb-test-fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff/gdb/testsuite/gdb.base/argv0-symlink-filelink"^M
(gdb) PASS: gdb.base/argv0-symlink.exp: kept file symbolic link name
