Fix long long little endian detection when cross-compiling

The long long endian detection code does an AC_TRY_RUN() and since that
doesn't work when cross-compiling, it sets a fallback value.  However,
rather than do any sort of default endian detection, the code simply
sets it to "no".  This probably breaks most little endian systems out
there when cross-compiling for them.  It certainly breaks Blackfin
systems.  So use the common endian detection code provided by autoconf
and key off of that when cross-compiling.

* configure.ac: Call AC_C_BIGENDIAN.
* m4/long_long.m4 (AC_LITTLE_ENDIAN_LONG_LONG): Set cross-compiling
logic based on ac_cv_c_bigendian.
