No, this is not what U32_ALIGNMENT_REQUIRED is about, it is the wrong
macro to test.

It wants 16 bit values or 32 bit values, and sparc requires natural alignemnt
for pointers to that. U32_ALIGNMENT_REQUIRED talks about alignment requirement
when it really wants to access character (8 bit) values, and there are no
such alignment requirements for sparc. The configure script is fine, the
code using U32_ALIGNMENT_REQUIRED for this case is not.
