In 25c3160092d7 ("uClibc 0.9.31: remove stray kludges/conditions"), a
conditional that prevents the combination gcc 4.2-avr / C++ / locale
with uClibc 0.9.31 was removed. However, it turns out that the same
problem is affecting uClibc 0.9.33, described at
http://comments.gmane.org/gmane.comp.lib.uclibc.buildroot/24260.
Therefore, we prevent the combination of gcc 4.2-avr / C++ / locale to
happen.

Enable this option if you want your toolchain to support the
C++ language and you want C++ libraries to be installed on
your target system.
