Please describe the problem:
tar-1.15.91 changed behaviour to not supporting shell-style globbing on the commandline by default.  however, the libxml2 xstc testsuite depends on this.

this patch passes the --wildcards option to tar to restore default behaviour.  this option has been supported since tar-1.13.20 which was released 2001-08-27.

Steps to reproduce:
1. ./configure
2. make
3. make test


Actual results:
