mangling of va_list on arm to conform to a newer revision of the EABI
specification. Codeblocks is built with ports gcc (4.9) but depends
on wxwidgets which has va_list in a public symbol in the form of
wxString::FormatV() and wxwidgets is built with base gcc (4.2.1).
This can be revisited when wxwidgets is built with a different compiler.
