[PATCH] ld: Make ARC's tls_ie-01 test more flexible

[Shahab Vahedi]

From: Shahab Vahedi <shahab@synopsys.com>

This is to address the regressions addressed by Nic [1].

The regular expression pattern for the tls_ie-01 test was
too strict and raising false alarms.  The new pattern only
looks for matches that should be there AND ignores the boiler
plates from the object dump.

	* testsuite/ld-arc/tls_ie-01.d: Use a more general pattern.
