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,

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.cc (LINK_COMMAND_SPEC): Remove mudflap spec handling.
