This patch works around a libstdc++ testsuite issue:  the generated 
program that tests for the availability of named locales dereferences 
invalid pointers on targets that don't allow command-line arguments to 
be passed.  (In particular, I ran into this with a simulator for an 
embedded target that produces a ton of verbose error messages when it 
hits an invalid memory reference.)  Jonathan already approved the fix in 
the issue, so I've gone ahead and checked it in.
