Debugger: Make rvalue dumper pass

Browse Source 
Depending on whether DWARF-2 or DWARF-4 is used, compilers encode
rvalue references as lvalue reference or rvalue references.

GDB doesn't understand rvalues, and there's no workaround, so restrict
the test to compiler version that use DWARF-2 by default.
(see https://sourceware.org/bugzilla/show_bug.cgi?id=14441)
