Makefile Fragments

   When you configure GCC using the `configure' script (*note
Installation::.), it will construct the file `Makefile' from the
template file `Makefile.in'.  When it does this, it will incorporate
makefile fragment files from the `config' directory, named `t-TARGET'
and `x-HOST'.  If these files do not exist, it means nothing needs to
be added for a given target or host.
