[PATCH] gas: Default to V8+ on 32-bit Solaris/SPARC

[Jose E. Marchesi]

Hello Rainer.

This is OK.
Thanks.

> While compilers default to v8plus on 32-bit Solaris/SPARC (gcc at least
> since 4.4 in 2009, cc since at least Stdio 9 in 2010), gas still uses a
> sparclite default.  While this doesn't cause issue for gcc (it passes
> -Av8plus as necessary), it repeatedly lead to problems in the testsuite
> which has to be sprinkled with setting ASFLAGS accordingly since gas cannot
> assemble the gcc output by default.

> This patch switches the default to v8plus on Solaris to match gcc.
> I had to introduce a new arch value, v8plus-32, matching v9-64, to allow
> for this.
>
> I cannot reliably tell if other SPARC targets are similarly affected, so
> this patch restricts the change to Solaris.
