 in the `Makefile` of `driver/mangler/` and `driver/split/`
 `$(INSTALL_PROGRAM)` is used to install the perl scripts (during make
 binary-dist).

 This fails under Solaris when `$(INSTALL_PROGRAM)` has a `-s` option to
 strip binaries.

 I've used a newer install-sh script in order to avoid bug #1810.
 A more clever install-sh script might ignore the `-s` switch for non-
 binaries.
