Cross-compiling C++ for the ICnova AP7000 base (AVR32) - unresolved references

[WANG.Jiong]

It seems your uClibc has not enabled the following feature

UCLIBC_HAS_WCHAR
UCLIBC_HAS_LOCALE
UCLIBC_HAS_XLOCALE

suggest you to check your libc with avr32-linux-nm to see if these
function's avaiable
if not, then check uClibc config file to make sure those feature macro
has been set
