Details:

Building octave from source on an ARM(v7) platform results in frequent cast
alignment warnings for many types, for example:


./util/oct-locbuf.h: In member function 'octave_local_buffer<double>::operator
double*() const':
./util/oct-locbuf.h:120:51: warning: cast from 'char*' to 'double*' increases
required alignment of target type [-Wcast-align]
     return reinterpret_cast<TYPE *> (this->data ()); \
                                                   ^
./util/oct-locbuf.h:133:1: note: in expansion of macro
'SPECIALIZE_POD_BUFFER'
 SPECIALIZE_POD_BUFFER (double);
