Linking problems using uClibc++

I'm trying to compile the px4 firmware for the px4_fmu-v5_default target with uClibc++ as C++ library. However, I get several undefined references in the linking phase (ld command):

- undefined reference to `operator delete(void*)'
- undefined reference to `__cxa_pure_virtual'
- undefined reference to `operator new[](unsigned int)'
- ...

Am I missing something in the configuration?
