  34 #  For bare targets, the $(config-vendor) is the name of the board.
  35 #  We will place the board dependent code ONLY in a library which
  36 #  is board dependent.  This way many target boards can share a
  37 #  single libc.a.  To resolve all symbols and successfully link
  38 #  a program, the application must link against libc.a and libMY_TARGET.a.
  39 #  For example, the target specific library for the Motorola MVME135
  40 #  board will be named libmvme135.a.  To link a program for the
  41 #  MVME135, one must link against -lc and -lmvme135.
