On a 32-bit SPARC userland, configure fails to compile assembly and the
build fails:
checking for options to compile assembly... configure: error: could not
compile assembly
config.log shows:
asm-tests/sparc64.S: Assembler messages:
asm-tests/sparc64.S:5: Error: Architecture mismatch on "lduw [%o4+4],%o4".

Simply moving these blocks earlier in configure.ac is sufficient to
ensure that the tests are executed with the appropriate flags
(specifically -m64 in this case).
