Between 20110421 and 20110429, all g++.dg/tree-prof and gcc.dg/{matrix, tree-prof}
execution tests started to fail on Solaris 8 and 9, both x86 and SPARC:

+FAIL: g++.dg/tree-prof/indir-call-prof-2.C execution,    -g  -fprofile-generate

spawn [open ...]
ld.so.1: indir-call-prof-2.x01: fatal: /var/gcc/regression/trunk/9-gcc-gas/build
/gcc/testsuite/g++/indir-call-prof-2.x01: object requires TLS, but TLS failed to
 initialize

This obviously happens since profiling now uses TLS under the hood:

[5]     |         4|       4|TLS  |LOCL |0    |9      |__gcov_indirect_call_callee
[6]     |         0|       4|TLS  |LOCL |0    |9      |__gcov_indirect_call_counters

So it is caused by this patch:

2011-04-27  Xinliang David Li  <davidxl@google.com>

        * tree-profile.c (init_ic_make_global_vars): Set
        tls attribute on ic vars.
        * coverage.c (coverage_end_function): Initialize
        function_list with zero.

Some platforms require special options for TLS, which is handled by
dg-add-options tls.  It seems that all tests in those directories should be
marked

  dg-require-effective-target tls_runtime
  dg-add-options tls

or rather this should be handled in the .exp files instead.
