proposed fix to gas/configure.tgt for sparcv9*

After configuring binutils --build=sparcv9-sun-solaris2.11, I expected that gas(1) would not just be a 64-bit executable, but that it would generate 64-bit objects by default, similar to GCC.  Instead, it generates 32-bit objects by default.  
After some digging I found that gas/configure.tgt currently checks for a number of variants of sparc, but eventually hits 'sparc*' and sets arch to 'sparclite'.  It seems like sparcv9 and sparc64 should be equivalent and set arch=v9-64,

    When configuring GAS treat as sparcv9 target the same way as a sparc64 target.
    
    	PR gas/20992
    	* configure.tgt: Treat sparcv9 as sparc64.
