CFLAGS and CXXFLAGS must not be set during the building of
cross-tools.
To disable CFLAGS and CXXFLAGS use the following commands:
unset CFLAGS unset CXXFLAGS
Now add these to ~/.bashrc, just in
case you have to exit and restart building later:
echo unset CFLAGS >> ~/.bashrc echo unset CXXFLAGS >> ~/.bashrc
