[parisc-linux-cvs] devel gcc fixes

[Alan Modra]

A couple of fixes.  The makefile change stops an x86 object being 
included when cross-compiling a native hppa-linux gcc.  ie.
--build=i686-linux --host=hppa-linux --target=hppa-linux

The pa change fixes "unaligned access" crash on this rtl.

            (asm_operands/v ("ssm %0,%%r0") ("") 0

                ] 
                [ 
                    (asm_input:SI ("i"))
                ]  ("init/main.c") 571)

        ] ) -1 (insn_list 105 (nil))
