Thanks.  Then a simple configure check with AC_MSG_ERROR([little-endian 
powerpc32 not supported]) will be a good idea to detect any attempts to 
build such a configuration at as early a build stage as possible, and to 
make clear there isn't any supported ABI for that combination (so that if 
support for it were added in future it might have different symbol 
versions, for example).
