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:

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).

Depending on the OS/libc, device macros are defined in different
headers. This change ensures we include the right one.
sys/types.h - BSD
sys/mkdev.h - Sun
sys/sysmacros.h - glibc (Linux)
glibc currently pulls sys/sysmacros.h into sys/types.h, but this may
change in a future release.
