SH config files still refer to flag_new_abi

Not quite.  Actually, we had an actidental slippage to word-sized bools
when SLOW_BYTE_ACCESS got defined, so I made the use of wide bools
conditional on flag_new_abi to preserve binary compatibility.

You may do this on the fsf gcc mainline, but don't merge it in any branches
that still have the old definition of BOOL_TYPE_SIZE in gcc/cp/decl.c,
since that would actually force wide bools unless you specify -fnew-abi.
