The target tuple @code{sparc-sun-solaris} will be used for
configurations in which only 32-bit SPARC binaries may be executed;
@code{sparcv9-sun-solaris} will be used when either 32-bit or 64-bit
binaries may be executed, but the compiler will produce 32-bit
binaries unless the @option{-m64} switch is used; @code{sparc64-sun-solaris}
should be used when the compiler should produce 64-bit binaries
by default.
Unless otherwise specified, @command{configure} will select either
@code{sparc} or @code{sparcv9} based on the output of @command{isalist}.
It will never select @code{sparc64} by default.
