* regint.h (PLATFORM_UNALIGNED_WORD_ACCESS): The value of
UNALIGNED_WORD_ACCESS should be used to determine whether
unaligned word access is allowed or not. After this commit,
./configure CPPFLAGS="-DUNALIGNED_WORD_ACCESS=0" disables
unaligned word access even on platforms that support the feature.
