toolchain: disable C++ support on AVR32 gcc 4.2 with uClibc
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. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

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.
