[src/fpif.c] No longer assume that if HAVE_BIG_ENDIAN is not defined,
the architecture is little endian. Detect the case where neither
HAVE_BIG_ENDIAN nor HAVE_LITTLE_ENDIAN is defined (currently an
error).
[configure.ac] Fixed the use of AC_C_BIGENDIAN (since AC_CONFIG_HEADERS
is not used, one must have an ACTION-IF-UNIVERSAL argument).
[doc/README.dev] Check with "-UHAVE_BIG_ENDIAN -UHAVE_LITTLE_ENDIAN"
(unknown/unspecified endianness) before a release.
