Remove all files from the following directories:

   binutils
   gas
   gdb/gdbtk
   gold
   gprof
   itcl
   ld
   libgui
   winsup

The offending files in those directories had been pulled in by runs
of "git cvsimport" (it failed to exclude the directories excluded in
the initial cvs-to-git conversion).  I've added gdb/gdbtk to the list
of excluded directories on the advice of Tom Tromey, and because its
presence make a stock "./configure && make" fail due to absence of tcl
configuration bits.
