Hi,

Here is a patch for fixing profiling support in GNU/Hurd, to be applied
on top of my previous pthread patch.

      * gcc/config/i386/gnu.h (STARTFILE_SPEC): Use gcrt0.o in profile mode, add
      -profile option, add pie support.
      (ENDFILE_SPEC): New spec.
      * gcc/config/gnu.h (LIB_SPEC): Add -profile option.
