Add "sparc" host cpu to configure.ac

Some sparc Debian setups advertise a "sparc" host cpu (rather than
sparc64).

In all cases, I think it should be safe to add a "sparc" entry to
userspace RCU configure.ac upstream, e.g.

        [sparc], [ARCHTYPE="sparc64"],

in the event someone would launch the build on an environment not
supporting sparc v9, the build would fail because the 32-bit compiler
would not be able to generate sparc v9 instructions (unless
explicitely instructed to do so by the -m32 -Wa,-Av9a flags).
