[commited] Remove a couple mudflap remnants

I happened to be digging into the specs to understand a build failure 
and spotted mflib and mfwrap.  Those were used by the mudflap system 
which we ripped out years ago and we just missed these.

I verified x86 still bootstraps after removing these bits.

Pushed to the trunk as obvious,

Jeff

    Remove a couple mudflap remnants
    
    I happened to be digging into the specs to understand a build
    failure and spotted mflib and mfwrap.  Those were used by the
    mudflap system which we ripped out years ago and we just missed
    these.
    
    I verified x86 still bootstraps after removing these bits.
    
    Pushed to the trunk as obvious,
    gcc/
            * gcc.cc (LINK_COMMAND_SPEC): Remove mudflap spec handling.
