[PATCH] CPP fixes for x86_64-netbsd on 3.1 branch

[Jason R Thorpe]

These were applied to the trunk, but missed the 3.1 cut-off.

Committed to 3.1 branch.

        * config/i386/netbsd64.h (CPP_LP64_SPEC): Define.
        (CPP_SUBTARGET_SPEC): Define.
        (SUBTARGET_EXTRA_SPECS): Redefine, adding cpp_lp64 and
        cpp_subtarget specs. 
        (CPP_SPEC): Redefine to include %(cpp_subtarget).
