The testsuite for PR52796 uses the 'target c++11' selector which doesn't exist in 4.6. This patch backports the selector, clearing the 'ERROR: g++.dg/cpp0x/variadic-value1.C: syntax error in target selector "target c++11" for " dg-do 2 run { target c++11 } "' errors which have appeared in recent 4.6 builds.
Tested on x86_64-linux-gnu with no regressions. Changes the ERROR to UNSUPPORTED.
